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 one-eighth of a hundredweight, which is 112 pounds, and one-quarter 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

  • 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.
