How to convert 1 stone (st) = 0.006350293 tonne (tonne).
Stone (st) is a unit of Weight used in Standard system.
Tonne (tonne) is a unit of Weight used in Metric system. Stones: A Unit of Weight
Stones are a unit of weight that are used in the British imperial system and the US customary system. Stones are derived from the use of stones for weights, a practice that dates back to ancient times. The word stone comes from the Old English stan, meaning stone, and the abbreviation st comes from the Latin word statera, meaning balance.
Definition of the Stone
The stone is defined as 14 pounds avoirdupois, which is equal to 6.35 kilograms or 224 ounces. The avoirdupois pound is defined as 7000 grains, which is a unit of mass based on the weight of a grain of wheat. The stone is oneeighth of a hundredweight, which is 112 pounds, and onequarter of a quarter, which is 28 pounds.
The stone is not a legal unit of measurement in most countries, except for the United Kingdom and Ireland, where it is still used for measuring body weight. In other countries, such as the United States, Canada, Australia and New Zealand, the stone is sometimes used informally for expressing human weight.
How to Convert Stones
Stones can be converted to other units of weight by using conversion factors or formulas. Here are some examples of how to convert stones to other units of weight in the US customary system and the SI system:
 To convert stones to pounds, multiply by 14. For example, 10 st = 10 x 14 = 140 lb.
 To convert stones to ounces, multiply by 224. For example, 5 st = 5 x 224 = 1120 oz.
 To convert stones to tons (short), divide by 142.857. For example, 20 st = 20 / 142.857 = 0.14 ton.
 To convert stones to kilograms, multiply by 6.35. For example, 8 st = 8 x 6.35 = 50.8 kg.
 To convert stones to grams, multiply by 6350. For example, 3 st = 3 x 6350 = 19050 g.
 To convert stones to milligrams, multiply by 6350000. For example, 2 st = 2 x 6350000 = 12700000 mg.
Where Stones are Used
Stones are used in different countries and regions for different applications and purposes. Here are some examples of where stones are used:
 In the United Kingdom and Ireland, stones are used for measuring body weight and livestock weight. For example, a person may weigh 11 st or a cow may weigh 40 st.
 In the United States, stones are sometimes used for measuring body weight and sports equipment. For example, a boxer may weigh 12 st or a bowling ball may weigh 1 st.
 In Canada, Australia and New Zealand, stones are sometimes used for measuring body weight and agricultural products. For example, a person may weigh 9 st or a bag of potatoes may weigh 2 st.
 In some African countries, such as Kenya and Uganda, stones are sometimes used for measuring crops and commodities. For example, a sack of maize may weigh 4 st or a bunch of bananas may weigh 1 st.
History of Stones
Stones have a long history that dates back to ancient times. Here are some highlights of the history of stones:
 The stone was an ancient unit of measurement that was based on the weight of a natural stone or rock. It varied from place to place and from time to time depending on the type and size of the stone used.
 The stone was used in different systems of measurement, such as the Roman system, the AngloSaxon system, the English system and the Scottish system. It ranged from about 5 pounds to about 40 pounds depending on the region and the object weighed.
 The stone was standardized by royal statutes and international agreements in different periods of history. For example, in 1389 a royal statute fixed the stone of wool at 14 pounds in England; in 1824 an international agreement defined the avoirdupois pound as exactly 453.59237 grams; in 1835 an act permitted using a stone of 14 pounds for trade in Britain; in 1959 an international agreement defined the international avoirdupois ounce as exactly 28.349523125 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.
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.
