How to convert 1 troy ounce (oz t) = 3.11035E05 tonne (tonne).
Troy Ounce (oz t) is a unit of Weight used in Standard system.
Tonne (tonne) is a unit of Weight used in Metric system. 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 seventhousandth 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.

Tonnes: A Unit of Weight
Tonnes are a unit of weight that are used for measuring large masses, such as vehicles, ships, and buildings. Tonnes are also known as metric tons or megagrams. The symbol for tonne is t.
Definition of the Tonne
The tonne is defined as 1000 kilograms, which is the base unit of mass in the International System of Units (SI). The tonne is also equal to one million grams or one billion milligrams.
The tonne is equal to about 2204.6 avoirdupois pounds or 1.1023 short tons. The tonne is also equal to about 0.9842 long tons or 0.9072 tonnesforce.
How to Convert Tonnes
Tonnes can be converted to other units of weight by using conversion factors or formulas. Here are some examples of how to convert tonnes to other units of weight in the US customary system and the SI system:
 To convert tonnes to avoirdupois pounds, multiply by 2204.6226. For example, 10 t = 10 x 2204.6226 = 22046.226 lb.
 To convert tonnes to short tons, multiply by 1.1023. For example, 5 t = 5 x 1.1023 = 5.5115 st.
 To convert tonnes to long tons, multiply by 0.9842. For example, 20 t = 20 x 0.9842 = 19.684 lt.
 To convert tonnes to kilograms, multiply by 1000. For example, 15 t = 15 x 1000 = 15000 kg.
 To convert tonnes to grams, multiply by 1000000. For example, 25 t = 25 x 1000000 = 25000000 g.
 To convert tonnes to milligrams, multiply by 1000000000. For example, 30 t = 30 x 1000000000 = 30000000000 mg.

History of Tonnes
Tonnes have a relatively short history that dates back to the late 18th century. Here are some highlights of the history of tonnes:
 The tonne was originally based on the weight of a cubic meter of water at its maximum density of four degrees Celsius, which was approximately equal to 1000 kilograms.
 The tonne was part of the original metric system that was introduced in France in 1795 as a decimalbased system of measurement that was designed to replace the traditional units that varied from region to region.
 The tonne was adopted by many countries around the world as part of the International System of Units (SI) that was established in 1960 as a universal system of measurement that was based on seven base units and several derived units.
 The tonne was also referred to as the metric ton or the megagram in some countries and contexts to distinguish it from the nonmetric units of the short ton and the long ton.
