This is the ounce that is used for most purposes, such as measuring food, postal items, fabric, paper and boxing gloves.

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 one-twelfth 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.

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

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.

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.
