Pounds: A Unit of Weight

Definition of the Pound

A pound is a unit of weight that measures how much force an object or substance exerts on a scale due to gravity. It is equal to 0.45359237 kilograms, or 16 ounces, or 7000 grains. One pound can also be written as lb or lbs.

History of the Pound

The pound was originally defined in ancient Rome as the mass of a bronze bar called a libra, which was divided into 12 ounces. The libra was later adopted by various regions and countries in Europe, such as England, France and Germany, with different values and subdivisions.

The pound as we know it today is based on the avoirdupois system, which was developed in the 13th century in France and England. The avoirdupois pound was standardized in 1959 by an international agreement among the United States, Canada, Australia, New Zealand and South Africa as exactly 0.45359237 kilograms.

The pound, as well as other units of weight, such as the ounce and the ton, were introduced in the 19th century as part of the imperial system of measurement that aimed to unify the units used in the British Empire. The pound was officially adopted by the International System of Units (SI) in 1960 as one of the seven base units.

How to Convert Pounds

To convert pounds to other units of weight, we need to use conversion factors that relate the pound to the desired unit. For example, to convert pounds to kilograms, we need to know that one kilogram is equal to 2.2046226218 pounds. Therefore, one pound is equal to 0.45359237 kilograms.

Here are some common conversion factors for pounds:

• 1 lb = 0.45359237 kg
• 1 lb = 16 oz
• 1 lb = 7000 gr
• 1 lb = 0.0005 t
• 1 lb = 0.0714285714 st

To convert from other units of weight to pounds, we need to use the inverse of these conversion factors. For example, to convert kilograms to pounds, we need to multiply by 2.2046226218.

Where Pounds are Used

The pound is a unit of weight that is widely used in the United States and some other countries that have historical ties with Britain, such as Canada and Australia. It is commonly used to measure the weight of people, animals, food, clothes and other everyday items. For example, an average adult male in the United States has a weight of about 198 lbs.

The pound is also used to measure some physical quantities such as force, pressure and torque. For example, one pound-force (lbf) is equal to one pound times the standard acceleration due to gravity (32.174 ft/s²).

Example Conversions of Pounds to Other Units

Here are some examples of how to convert pounds to other units of weight using the conversion factors given above:

• 2 lb = 2 x 0.45359237 kg = 0.90718474 kg
• 3 lb = 3 x 16 oz = 48 oz
• 4 lb = 4 x 7000 gr = 28000 gr
• 5 lb = 5 x 0.0005 t = 0.0025 t
• 6 lb = 6 x 0.0714285714 st = 0.4285714284 st

Conclusion

The pound is a unit of weight that measures how much force an object or substance exerts on a scale due to gravity. It is equal to 0.45359237 kilograms, or 16 ounces, or 7000 grains. The pound is widely used in the United States and some other countries that have historical ties with Britain, such as Canada and Australia, as well as some physical quantities such as force, pressure and torque. To convert pounds to other units of weight, we need to use conversion factors that relate the pound to the desired unit.

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.

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 Anglo-Saxon 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.
