How to convert 1 tonne (tonne) = 35273.96195 ounce (oz).
Tonne (tonne) is a unit of Weight used in Metric system.
Ounce (oz) is a unit of Weight used in Standard system. 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.
Where Tonnes are Used
Tonnes are used in different countries and regions for different applications and purposes. Here are some examples of where tonnes are used:
 In most countries that use the SI system, tonnes are used for measuring weight, especially for large masses, such as vehicles, ships, and buildings.
 In the United States, tonnes are sometimes used for measuring weight, especially for international trade and commerce.
 In Canada, Australia and New Zealand, tonnes are sometimes used for measuring weight, especially for international trade and commerce.
 In the United Kingdom, tonnes are sometimes used for measuring weight, especially for international trade and commerce.
 In India, tonnes are sometimes used for measuring weight, especially for international trade and commerce.
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.
Example Conversions of Tonnes to Other Units
Here are some examples of conversions of tonnes to other units of weight:
 1 t = 2204.6226 lb
 1 t = 1.1023 st
 1 t = 0.9842 lt
 1 t = 1000 kg
 1 t = 1000000 g
 1 t = 1000000000 mg
 1 t = 32.1507 oz t
 1 t = 643.0149 dwt
 1 t = 15432.3584 gr
 1 t = 0.001 kN
Tonne also can be marked as Metric Ton. Definition of the Ounce
The ounce is defined differently in different systems of measurement. The most common ounce is the international avoirdupois ounce, which is equal to 28.349523125 grams or 437.5 grains. This is the ounce that is used for most purposes, such as measuring food, postal items, fabric, paper and boxing gloves. The avoirdupois ounce is onesixteenth of an avoirdupois pound, which is defined as 7000 grains.
Another ounce is the international troy ounce, which is equal to 31.1034768 grams or 480 grains. This is the ounce that is used for measuring precious metals and gems, such as gold, silver, platinum and diamonds. The troy ounce is onetwelfth of a troy pound, which is defined as 5760 grains.
A third ounce is the apothecaries’ ounce, which is also equal to 480 grains, but it is divided into eight drams instead of twelve pennyweights like the troy ounce. The apothecaries’ ounce is used for measuring medicines and drugs.
There are also other historical or regional ounces that have different values, such as the Spanish ounce, the French ounce, the Portuguese ounce, the Roman/Italian ounce, the Dutch metric ounce and the Chinese metric ounce.
How to Convert Ounces
Ounces can be converted to other units of weight by using conversion factors or formulas. Here are some examples of how to convert ounces to other units of weight in the US customary system and the SI system:
 To convert ounces to pounds, divide by 16. For example, 32 oz = 32/16 = 2 lb.
 To convert ounces to tons (short), divide by 32000. For example, 64000 oz = 64000/32000 = 2 tons.
 To convert ounces to grams, multiply by 28.349523125. For example, 4 oz = 4 x 28.349523125 = 113.3980925 g.
 To convert ounces to kilograms, multiply by 0.028349523125. For example, 8 oz = 8 x 0.028349523125 = 0.226796185 kg.
 To convert ounces to milligrams, multiply by 28349.523125. For example, 2 oz = 2 x 28349.523125 = 56699.04625 mg.
 To convert ounces to micrograms, multiply by 28349523.125. For example, 1 oz = 1 x 28349523.125 = 28349523.125 µg.
Where Ounces are Used
Ounces are used in different countries and regions for different applications and purposes. Here are some examples of where ounces are used:
 In the United States, ounces are used for measuring packaged foods and food portions, postal items, areal density of fabric and paper, boxing gloves and firearms.
 In the United Kingdom, ounces are used for measuring food portions and ingredients, woolen cloth and gold bullion.
 In Canada, ounces are used for measuring food portions and ingredients, precious metals and gems and liquor bottles.
 In Australia and New Zealand, ounces are used for measuring food portions and ingredients, precious metals and gems and baby weights.
 In China, ounces are used for measuring tea leaves and pearls.
 In India, ounces are used for measuring gold ornaments and silk fabrics.
History of Ounces
Ounces have a long history that dates back to ancient times. Here are some highlights of the history of ounces:
 The uncia was an ancient Roman unit of measurement that was onetwelfth of a Roman pound or libra. It was also used as a unit of volume and area.
 The uncia was borrowed into Old English as ynsan or yndsan from a Vulgar Latin form with ts for c before i (palatalization). This became inch in modern English.
 The uncia was also borrowed into Middle English through AngloNorman and Middle French as unce, once or ounce. This became ounce in modern English.
 The ounce was divided into different fractions and multiples, such as the dram, the pennyweight, the scruple and the mark.
 The ounce was used in different systems of measurement, such as the imperial system, the US customary system, the troy system and the apothecaries’ system.
 The ounce was standardized by international agreements, such as the international yard and pound agreement of 1959 and the international troy ounce agreement of 1958.
