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.

An Introduction to Hectograms

Hectograms are a unit of mass in the metric system that are equal to one hundred grams. They are rarely used in everyday life, but they have some specific applications in agriculture, retail and radio astronomy. In this article, we will explore the definition, history, conversion and usage of hectograms.

Definition of Hectograms

A hectogram is “a metric unit of mass equal to one hundred grams”, according to the Oxford Dictionaries. The symbol for hectogram is hg, and it is derived from the Greek word “hekatón”, meaning “hundred”. A hectogram is also equivalent to 0.1 kilogram, 3.527 ounces or 487.76 carats.

History of Hectograms

Hectograms were introduced as a multiplier in the metric system in 1795, along with other prefixes such as kilo, deca, deci and centi. The metric system was developed in France during the French Revolution, as a way to standardize and simplify measurements. The metric system was based on decimal fractions and powers of ten, unlike the previous systems that used arbitrary units and fractions.

The metric system was adopted by many countries in the 19th and 20th centuries, and became the official system of measurement for science and international trade. However, some countries such as the United States still use other systems such as the imperial or customary units.

How to Convert Hectograms

Hectograms can be easily converted to other units of mass by multiplying or dividing by powers of ten. For example, to convert hectograms to grams, we multiply by 100; to convert hectograms to kilograms, we divide by 10; to convert hectograms to milligrams, we multiply by 100000.

Where Hectograms are Used

Hectograms are not very common in everyday life, but they have some specific applications in different fields and countries. Here are some examples:

• In agronomy, hectograms are used for measuring quantities of animal feed (hectogram/animal) and for measuring agricultural productivity (hectogram/hectare).
• In Italy, hectograms are used for retail sale of cold cuts and meat, and are abbreviated as etto.
• In Canada, New Zealand and Sweden, hectograms are sometimes used for labeling packages of cheese and meat.
• In radio astronomy, hectograms are occasionally used to indicate a radio band by wavelength (hectometre).

Example Conversions of Hectograms to Other Units

Here are some example conversions of hectograms to other units:

• To convert 2 hg to g, we multiply by 100: 2 hg x 100 = 200 g
• To convert 5 hg to kg, we divide by 10: 5 hg / 10 = 0.5 kg
• To convert 3 hg to mg, we multiply by 100000: 3 hg x 100000 = 300000 mg
• To convert 4 hg to oz, we multiply by 3.527: 4 hg x 3.527 = 14.108 oz
• To convert 6 hg to lb, we multiply by 0.22: 6 hg x 0.22 = 1.32 lb
• To convert 7 hg to ct, we multiply by 487.76: 7 hg x 487.76 = 3414.32 ct
