Kilograms: A Unit of Weight

Definition of the Kilogram

A kilogram 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 the mass of the International Prototype of the Kilogram (IPK), a cylinder of platinum-iridium alloy stored at the International Bureau of Weights and Measures in France. One kilogram can also be written as kg or 1000 g.

History of the Kilogram

The kilogram was originally defined in 1795 during the French Revolution as the mass of one litre of water at 4 °C, which was determined to be 18841 grains. In 1799, the Kilogramme des Archives, a platinum artifact, replaced it as the standard of weight. In 1889, the IPK became the new standard of the unit of weight for the metric system and remained so for 130 years, until the current definition was adopted in 2019.

The kilogram, as well as other metric units of weight, such as the gram and the tonne, were introduced in the 19th century as part of the decimal system of measurement that aimed to simplify and unify the units used in science and commerce. The kilogram was officially adopted by the International System of Units (SI) in 1960 as one of the seven base units.

How to Convert Kilograms

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

Here are some common conversion factors for kilograms:

  • 1 kg = 1000 g
  • 1 kg = 2.2046226218 lb
  • 1 kg = 35.27396195 oz
  • 1 kg = 0.001 t
  • 1 kg = 0.1574730444 st

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

Where Kilograms are Used

The kilogram is a unit of weight that is widely used to measure the weight of objects and substances such as food, clothes, animals, metals and chemicals. For example, an adult human body has an average weight of about 62 kg.

The kilogram is also used to measure the weight of some physical quantities such as force, pressure and torque. For example, one newton (N) is equal to one kilogram times one meter per second squared (kg x m/s2).

Example Conversions of Kilograms to Other Units

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

  • 2 kg = 2 x 1000 g = 2000 g
  • 3 kg = 3 x 2.2046226218 lb = 6.6138678654 lb
  • 4 kg = 4 x 35.27396195 oz = 141.0958478 oz
  • 5 kg = 5 x 0.001 t = 0.005 t
  • 6 kg = 6 x 0.1574730444 st = 0.9448382664 st

Conclusion

The kilogram 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 the mass of the IPK, a cylinder of platinum-iridium alloy stored in France. The kilogram is widely used to measure the weight of objects and substances such as food, clothes, animals, metals and chemicals, as well as some physical quantities such as force, pressure and torque. To convert kilograms to other units of weight, we need to use conversion factors that relate the kilogram to the desired unit.

Kilograms also can be marked as kilogrammes in UK.

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.
