When buying or selling precious metals, a unit of measurement that is unfamiliar to many is the ounce. Much simpler and clearer, we are used to Everyday life Use the metric system, measure weight in grams. However, in international practice, this is the standard for determining the value of precious metals. The answer to the question: 1 ounce, how many grams, is not as simple as it might seem at first glance.
Translation problems
Translation problems arise due to the presence of different names depending on the field of use and the country where it is used. Adding to the confusion is the fact that some countries, such as the United States, still do not use the metric system, preferring the traditional one.
- Avoirdupois (oz or oz at) – 28.35 g, used by the USA as a measure of weight.
- Fluid ounce (fl oz) – 29.573 531 ml, used to determine the volume of liquid.
- Troy ounce (toz or ozt) – 31.1034768 g, this value is used throughout the world to measure the weight of precious metals.
Troy ounce
The troy ounce is a generally accepted measure for precious metals.
Simplified meaning for translation: 1 ozt – 31.1035 grams.
It should be noted that in international trade this unit is used only to determine the mass of pure metals of the highest standard.
On world currency markets, the XAU index is used to indicate the rate of 999.9 gold. Mints different countries coins weighing 31.1 g are minted. Many, both old and modern money made of gold and silver, have this denomination.
origin of name
Uncia– Latin term means 1/12 part. This concept came to us from Ancient Rome, but the troy ounce appeared as a measure of weight much later. This name has nothing to do with ancient Troy and comes from the name of the French city Troyes(Troyes), Champagne province.
In the Middle Ages, famous champagne fairs were held here, where traders from different countries gathered. The presence of various measures led to the need to use some kind of unifying value.
This unit became the troy pound and its 1/12th part - the troy ounce. In the 19th century, Great Britain became the center of world trade. Which inherited and finally consolidated the use of this measure as the main one in international trade in precious metals.
Using recalculation in practice
The need to convert ounces to grams arises, in most cases, when trying to calculate silver per gram in national currency, for example in rubles, today. The calculation algorithm is quite complex and requires knowledge not only of the cost of the metal in dollars per ounce, but also of the ruble/dollar exchange rate. It looks like this:
the cost of gold (USD/ozt) divided by 31.1035 and multiplied by the exchange rate USD/RUB, we get the price of gold in RUB/g.
There is a calculator for calculating the cost of gold, which makes calculations based on data from the Central Bank, which makes it much easier and faster to get the desired result.
You can find a large number of unit converters on the Internet; when using such programs to convert the weight of precious metals, it is important to remember that you need a troy ounce, and not some other unit.

General information
Volume is the space occupied by a substance or object. Volume can also refer to the free space inside a container. Volume is a three-dimensional quantity, unlike, for example, length, which is two-dimensional. Therefore, the volume of flat or two-dimensional objects is zero.
Volume units
Cubic meter
The SI unit of volume is the cubic meter. Standard definition One cubic meter is the volume of a cube with edges one meter long. Derived units such as cubic centimeters are also widely used.
Liter
The liter is one of the most commonly used units in the metric system. It is equal to the volume of a cube with edges 10 cm long:
1 liter = 10 cm × 10 cm × 10 cm = 1000 cubic centimeters
This is the same as 0.001 cubic meters. The mass of one liter of water at a temperature of 4°C is approximately equal to one kilogram. Milliliters, equal to one cubic centimeter or 1/1000 of a liter, are also often used. Milliliter is usually denoted as ml.
Jill
Jills are units of volume used in the US to measure alcoholic drinks. One jill is five fluid ounces in the British Imperial system or four in the American system. One American jill is equal to a quarter of a pint or half a cup. Irish pubs serve strong drinks in portions of a quarter jill, or 35.5 milliliters. In Scotland, portions are smaller - one fifth of a jill, or 28.4 milliliters. In England, until recently, portions were even smaller, just one-sixth of a jill or 23.7 milliliters. Now, it’s 25 or 35 milliliters, depending on the rules of the establishment. The owners can decide for themselves which of the two portions to serve.
Dram
Dram, or drachma, is a measure of volume, mass, and also a coin. In the past, this measure was used in pharmacy and was equal to one teaspoon. Later, the standard volume of a teaspoon changed, and one spoon became equal to 1 and 1/3 drachms.
Volumes in cooking
Liquids in cooking recipes are usually measured by volume. Bulk and dry products in the metric system, on the contrary, are measured by mass.
Tea spoon
The volume of a teaspoon varies different systems measurements. Initially, one teaspoon was a quarter of a tablespoon, then - one third. It is the latter volume that is now used in the American measurement system. This is approximately 4.93 milliliters. In American dietetics, the size of a teaspoon is 5 milliliters. In the UK it is common to use 5.9 milliliters, but some diet guides and cookbooks use 5 milliliters. The size of a teaspoon used in cooking is usually standardized in each country, but different sizes of spoons are used for food.
Tablespoon
The volume of a tablespoon also varies depending on the geographic region. So, for example, in America, one tablespoon is three teaspoons, half an ounce, approximately 14.7 milliliters, or 1/16 of an American cup. Tablespoons in the UK, Canada, Japan, South Africa and New Zealand also contain three teaspoons. So, a metric tablespoon is 15 milliliters. A British tablespoon is 17.7 milliliters, if a teaspoon is 5.9, and 15 if a teaspoon is 5 milliliters. Australian tablespoon - ⅔ ounce, 4 teaspoons, or 20 milliliters.
Cup
As a measure of volume, cups are not defined as strictly as spoons. The volume of the cup can vary from 200 to 250 milliliters. A metric cup is 250 milliliters, and an American cup is slightly smaller, approximately 236.6 milliliters. In American dietetics, the volume of a cup is 240 milliliters. In Japan, cups are even smaller - only 200 milliliters.
Quarts and gallons
Gallons and quarts also have different sizes, depending on the geographic region where they are used. In the Imperial system of measurement, one gallon is equal to 4.55 liters, and in the American system of measurements - 3.79 liters. Fuel is generally measured in gallons. A quart is equal to a quarter of a gallon and, accordingly, 1.1 liters in the American system, and approximately 1.14 liters in the Imperial system.
Pint
Pints are used to measure beer even in countries where the pint is not used to measure other liquids. In the UK, milk and cider are measured in pints. A pint is equal to one-eighth of a gallon. Some other countries in the Commonwealth of Nations and Europe also use pints, but since they depend on the definition of a gallon, and a gallon has a different volume depending on the country, pints are also not the same everywhere. An imperial pint is approximately 568.2 milliliters, and an American pint is 473.2 milliliters.
Fluid ounce
An imperial ounce is approximately equal to 0.96 US ounces. Thus, an imperial ounce contains approximately 28.4 milliliters, and an American ounce contains approximately 29.6 milliliters. One US ounce is also approximately equal to six teaspoons, two tablespoons, and one eighth cup.
Volume calculation
Liquid displacement method
The volume of an object can be calculated using the fluid displacement method. To do this, it is lowered into a liquid of a known volume, a new volume is geometrically calculated or measured, and the difference between these two quantities is the volume of the object being measured. For example, if when you lower an object into a cup with one liter of water, the volume of the liquid increases to two liters, then the volume of the object is one liter. In this way, you can only calculate the volume of objects that do not absorb liquid.
Formulas for calculating volume
Volume geometric shapes can be calculated using the following formulas:
Prism: the product of the area of the base of the prism and the height.
Rectangular parallelepiped: product of length, width and height.
Cube: length of an edge to the third power.
Ellipsoid: product of semi-axes and 4/3π.
Pyramid: one third of the product of the area of the base of the pyramid and the height. Post a question in TCTerms and within a few minutes you will receive an answer.
Troyskaya ounce of gold, platinum, silver is 9.7% heavier than a similar ounce of Avoirdupois. It is not used for weighing precious metals in the jewelry industry, banks or stock exchanges. Confusion in concepts often leads to the fact that jewelry is sold on the Internet with a weight indicated in ounces, but which ones are not specified. Therefore, you need to find out which ounces are indicated by the seller, otherwise you may overpay for that same 9.7%.
In grams, an ounce of gold is equal to 31.104 g, it is calculated relative to the troy pound and is 1/12 of it. The unit of measurement is abbreviated "t oz", but sometimes "ozt" is used. Among modern ounces, the most massive in grams is the troy ounce of gold; in the old days the British used it as an apothecary measure of weight. Herbs, medicines, potions and mixtures were packaged weighing 31.104 grams.
Now the troy pound has fallen out of use, only the avoirdupois remains in English use, but the troy ounce has been preserved as a measure of weight for precious metals.
Many people assume that the name of the troy ounce is associated with the ancient Greek city of Troy, but historians do not think so. According to scientists, the name of the ounce was formed in the French province of Troyes Champagne, where the first fair was organized back in the 5th century. And in the 14th century it was the largest in Europe and became one of the main centers of all world trade.
Traders from many countries came to this market, and since different countries had their own weight measures, confusion arose when weighing goods. Each city in France then had its own measure of weight - the Cologne pound, the Toulouse pound, and in Troyes there was the Troy pound.
The first mention of the Troy pound dates back to 1390. So the merchants made the local measure of weight uniform for the entire fair and all goods began to be measured in troy ounces. Many countries adopted this French measure of weight, including the British.
U troy ounce of gold there was a fixed weight, and it was very convenient. In Europe at that time there was another measure of weight, which was called gran. This measure denoted the average weight of a grain of barley, but people have been arguing for centuries about what exactly the weight of the grain is and what grain can be considered average.
In 2015, a sharp jump in the price of gold was recorded on the ruble market. This phenomenon is associated with the devaluation of the Russian currency and its fall against the dollar and euro. For 1 gram of gold at the beginning of 2014 they asked for about 1,300 rubles, now the increase in price is over 70%. According to experts, if the devaluation of the ruble continues, the cost of 1 gram of gold will also increase.
In addition to data on how many grams an ounce of gold contains, since 1950 there has been information on the price of one unit of valuable elements. At that time, the price of an ounce of gold was $34.7. In 1973, there was a sharp jump in the value of gold.
So the price increased from 97 to 160 dollars per ounce. Then, in 1979-1980, the cost increased further and now an ounce of gold cost $300. Then the price of gold began to fall, so the cost of an ounce of gold fell from 600 to 299 conventional units.
In 2002, a new round of growth in the value of gold began. And for almost 15 years now they have been asking for ounce of gold more and more.
In bullion and on exchanges, 1 ounce of gold has a fixed price. But for jewelry stores and workshops, the settings that banks define are only the starting point. When determining the final price for a precious item, a markup is made on the work of the jeweler, accounting for the wages of sellers and maintenance costs retail outlets. Therefore, the final price per ounce of gold may differ greatly from the actual cost.
This circumstance has led to the fact that the demand for investment coins of the Central Bank of Russia has now fallen. People knowledgeable about this issue understand that the sample weighing 7.78 g is overpriced, so last years Investments increasingly went into European Philharmonic coins. Also popular is the American Eagle, which contains exactly 1 troy ounce, but the price differs from 1 ounce of gold, since this sign is platinum.
Although the Central Bank of Russia miscalculated in its sales policy, it continues to purchase precious metals. His storerooms contained 33,300,000 supplies ounces of gold, which were increased in February 2015 to 37,000,000 troy ounces.
In our turbulent times, one of the most important indicators of the reliability of the economic condition of a country is the totality of its gold reserves. When talking about the value of this yellow metal in one currency or another, they use a rather strange measure called the troy ounce of gold. For some reason, the cost of this metal is not reflected in grams. How did this happen, why is the universal weight unit not used when weighing gold? And how much does a troy ounce weigh in grams?
What is an "ounce"
The concept of the ounce was born in Ancient Rome. In those days, bronze coins were in circulation, which were divided into parts. The twelfth part of a bronze ancient Roman coin was called an ounce. In modern equivalent, its weight was just over 27 grams.
Over time, the ounce began to be used not only as currency unit. Since standards for minting coins were quite strictly observed in Rome, ounces became convenient for weighing small measures various substances. The price of gold has always been high, so the ounce was the best choice for weighing this metal. Over time, this small measure of scales spread throughout Europe.
How to convert troy ounce to grams
Converting troy ounces to grams is quite simple. It should be remembered that one troy ounce is equal to 31.1035 grams. Accordingly, to convert, you should multiply this value by the required number of ounces.
The English system has such a concept as a troy ounce. The name itself is borrowed from the name of the French city of Troyes. 1 ounce today is especially popular in indicating the mass of certain jewelry; it shows the weight. This type of measurement is also known in various other fields, such as cosmetology. Certain types of ingredients are designated by this term (their weight).
1 ounce is...
An ounce is a measure that was used in ancient times. In Rome, such a measure took place and its weight was 27.3 grams. IN ancient Ethiopia, and also in various cities of Europe there was such a measure of an ounce (Maria Teresa) - 31.1025 grams. In pharmacy, until the 27th year of the last century, the measure of one ounce was equal to 29.86 grams. During the transition to another system of measures in the Netherlands, a certain value was adopted for an ounce - and this is the weight of 100 grams. A certain designation was adopted for the troy ounce (depending on the type of metal):
- palladium - XPD;
- platinum - XPT;
- silver - XAG;
- gold - XAU.
Currently, one ounce is a measure that is used to denote metals (precious). One troy ounce is equal to 31.1034768 grams, which is one-twelfth of a pound, which is used to denote the weight of the gold metal in England. Gold coins are also measured in ounces, which indicates their actual weight. But the price of a particular coin is primarily influenced by its features, not just its mass. However, as a measure they resort to an ounce.
Ounce - how many grams?
People who want to buy gold are wondering: how many grams are in 1 ounce? Today, thanks to the Internet, you can calculate how many grams are in an ounce and convert the weight of the gold metal into ounces. It should be noted that today the international market still uses such a measure as an ounce as a unit of weight; it is equal to a certain value.
Let's say gold weighs 100 grams, then an ounce is equal to: 3.2151. Gold bars with the designation of this measure prevail over others with a weight indicator in grams. This is why it is so important to understand what an ounce is and how many grams it means. Understanding such a concept as the weight of an ounce, you can easily calculate how many grams a particular gold bar weighs. Today, the weight of an ounce can be calculated using a special calculator.
In order to understand the situation on the world market, it should be taken into account that throughout the world the cost of an ounce is expressed in dollars. This is customary in all countries of the world. 1 ounce in grams will represent a troy unit. This centuries-old tradition, despite some difficulty in perception by contemporaries, is still particularly stable in our times and there are no plans to change it.
From history - what is 1 ounce equal to?
The city of Troyes, which gave the name to the ounce, is located in the provincial region of Champagne, on the famous Seine River, in the northern part of France. The town has a great past, steeped in centuries-old history. In ancient times, when gold gained particular popularity, the designation was adopted - what is the equivalent and how much of 1 ounce is a gram. This allowed us to avoid many misunderstandings.
This measure began to be used especially actively during the emergence of folk fairs, which attracted traders and buyers from around the world. It was then that people first began to wonder: how much does an ounce weigh?
Merchants who in ancient times purchased gold exchanged it at special points; it was then that a universal unit of mass of gold was adopted, it was about an ounce. A standard system was adopted at fairs; it was very convenient in trading.
At first, the livre (French) was used, which contained the silver pound itself. Knowing how many grams are in one ounce can help you avoid many problems regarding buying and selling gold. Thanks to the ounce, today it is possible to calculate the value of gold on the world market. After all, this is precisely the measure that applies to gold bars and coins.
London fixing
The London fixing (gold price) sets the price of gold around the world. In London, this price is set as a result of a decision made by representatives of the world's five largest banks. These are players in the metals market, which are of particular value and demand throughout the world. The price is set twice a day, in the morning and after lunch: at 10:00 and at 15:00 (Moscow time: 13:30, 18:00). It is after this time that price fluctuations on the global precious metals market can be monitored.
In order to protect their enterprise during inflation and crisis, entrepreneurs resort to methods of investing their investments. Buying gold can help you avoid difficult moments. To do this, you need to know what an ounce is equal to and track the price of precious metals based on London fixing data. Methods of investing in gold to avoid problems in difficult times:
- gold bars (measured), gold bars are bought or sold in a bank (special documents are required);
- gold coins (collectible or investment);
- impersonal metal accounts (depositors buy impersonal gold metal stored in the account, and have the opportunity to receive either money or gold at any time).
Power
Today, gold coins are especially popular. Investment coins of this type have certain characteristics:
- value in terms of artistry and investment;
- have a solid circulation;
- investment coins have a special manufacturing technology - uncirculated;
- unlike others investment coins they are timed to coincide with certain events.
A distinctive feature of purely investment coins from collectible coins is profitability due to the increase in the value of the metals on the basis of which they are created. Knowing the state of affairs on the international market and having knowledge of weights, you can secure your business and make a good profit from buying and selling valuable metals.
