## Troy Ounces: A Unit of Weight

Troy ounces are a unit of weight that are used for measuring precious metals, such as gold, silver and platinum. Troy ounces are derived from the French word once, which was the name of a unit of weight used in the Middle Ages. The symbol for troy ounce is oz t.

## Definition of the Troy Ounce

The troy ounce is defined as 20 pennyweights, which are each 24 grains. The troy grain is equal to the avoirdupois grain, which is one seven-thousandth of an avoirdupois pound. The troy ounce is heavier than the avoirdupois ounce, but lighter than the apothecaries’ ounce.

The troy ounce is equal to about 1.0971 avoirdupois ounces or 31.1035 grams. The troy grain is equal to about 0.0648 milligrams.

## How to Convert Troy Ounces

Troy ounces can be converted to other units of weight by using conversion factors or formulas. Here are some examples of how to convert troy ounces to other units of weight in the US customary system and the SI system:

• To convert troy ounces to avoirdupois ounces, multiply by 1.0971. For example, 10 oz t = 10 x 1.0971 = 10.971 oz.
• To convert troy ounces to avoirdupois pounds, divide by 14.5833. For example, 5 oz t = 5 / 14.5833 = 0.343 lb.
• To convert troy ounces to tons (short), divide by 29166.67. For example, 20 oz t = 20 / 29166.67 = 0.000685 ton.
• To convert troy ounces to kilograms, divide by 32.1507. For example, 15 oz t = 15 / 32.1507 = 0.4666 kg.
• To convert troy ounces to grams, multiply by 31.1035. For example, 25 oz t = 25 x 31.1035 = 777.5875 g.
• To convert troy ounces to milligrams, multiply by 31103.4768. For example, 30 oz t = 30 x 31103.4768 = 933104.304 mg.

## Where Troy Ounces are Used

Troy ounces are used in different countries and regions for different applications and purposes. Here are some examples of where troy ounces are used:

• In most countries that use the SI system, troy ounces are not used for measuring weight, but only for measuring precious metals, such as gold, silver and platinum.
• In the United States, troy ounces are used for measuring precious metals, especially for gold and silver coins and bullion.
• In Canada, Australia and New Zealand, troy ounces are used for measuring precious metals, especially for gold and silver coins and bullion.
• In the United Kingdom, troy ounces are used for measuring precious metals, especially for gold and silver coins and bullion.
• In India, troy ounces are used for measuring precious metals, especially for gold and silver jewelry.

## History of Troy Ounces

Troy ounces have a long history that dates back to ancient times. Here are some highlights of the history of troy ounces:

• The troy ounce was originally based on the weight of a Roman uncia, which was one twelfth of a Roman libra or pound, which was equivalent to about 27 grams.
• The troy ounce was used in different systems of measurement, such as the Roman system, the Byzantine system, the Arabic system and the English system. It varied from about 26 grams to about 32 grams depending on the region and the time period.
• The troy ounce was standardized by royal statutes and international agreements in different periods of history. For example, in 1527 an act of Henry VIII fixed the troy ounce at exactly 480 grains; in 1828 an act of Congress adopted the troy ounce as the official unit of weight for coinage in the United States; in 1959 an international agreement defined the international avoirdupois ounce as exactly 28.349523125 grams, which made the troy ounce exactly 31.1034768 grams.

## Grams: A Unit of Weight

Grams are a unit of weight that are used in the International System of Units (SI), also known as the metric system. Grams are derived from the French word gramme, which was taken from the Late Latin term gramma, meaning a small weight. The symbol for gram is g.

## Definition of the Gram

The gram is defined as one one-thousandth of a kilogram, which is the base unit of mass in the SI. The kilogram is defined by taking the fixed numerical value of the Planck constant h to be 6.62607015 ×10 −34 when expressed in the unit J s, which is equal to kg m 2 s −1, where the meter and the second are defined in terms of c and ∆ν Cs. The Planck constant is a fundamental physical constant that relates the energy of a photon to its frequency.

The gram is a very small unit of weight, equivalent to about 0.035 ounces or 0.002 pounds. It is commonly used for measuring non-liquid ingredients in cooking, such as flour, sugar, salt and spices. It is also used for measuring small masses, such as jewelry, coins, medicines and chemicals.

## How to Convert Grams

Grams can be converted to other units of weight by using conversion factors or formulas. Here are some examples of how to convert grams to other units of weight in the US customary system and the SI system:

• To convert grams to ounces, divide by 28.349523125. For example, 100 g = 100 / 28.349523125 = 3.527 oz.
• To convert grams to pounds, divide by 453.59237. For example, 500 g = 500 / 453.59237 = 1.102 lb.
• To convert grams to tons (short), divide by 907184.74. For example, 1000 g = 1000 / 907184.74 = 0.0011 ton.
• To convert grams to kilograms, divide by 1000. For example, 200 g = 200 / 1000 = 0.2 kg.
• To convert grams to milligrams, multiply by 1000. For example, 50 g = 50 x 1000 = 50000 mg.
• To convert grams to micrograms, multiply by 1000000. For example, 10 g = 10 x 1000000 = 10000000 µg.

## Where Grams are Used

Grams are used in different countries and regions for different applications and purposes. Here are some examples of where grams are used:

• In most countries that use the SI system, grams are used for measuring food portions and ingredients, postal items, drugs and medicines, precious metals and gems and scientific experiments.
• In the United States, grams are sometimes used for measuring food portions and ingredients, especially for nutritional information labels, drugs and medicines, precious metals and gems and scientific experiments.
• In Canada, grams are used for measuring food portions and ingredients, postal items, drugs and medicines, precious metals and gems and scientific experiments.
• In Australia and New Zealand, grams are used for measuring food portions and ingredients, postal items, drugs and medicines, precious metals and gems and scientific experiments.
• In China, grams are used for measuring food portions and ingredients, postal items, drugs and medicines, precious metals and gems and scientific experiments.

## History of Grams

Grams have a long history that dates back to ancient times. Here are some highlights of the history of grams:

• The gram was originally defined in 1795 as the absolute weight of a volume of pure water equal to the cube of the hundredth part of a meter at the temperature of melting ice.
• The gram was later changed to be the weight of a volume of pure water equal to the cube of the hundredth part of a meter at the temperature of maximum density of water (4 °C).
• The gram was part of the centimeter–gram–second system of units (CGS) that was developed in the 19th century as an alternative to the meter–kilogram–second system of units (MKS).
• The gram was replaced by the kilogram as the base unit of mass in the SI system that was adopted in 1960 as an international standard for measurements.
• The gram was redefined in terms of the kilogram and the Planck constant in 2019 as part of a major revision of the SI system.
