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

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.

Milliliters - A Unit of Volume

Definition of the Milliliter

A milliliter (international spelling) or milliliter (American English spelling) (SI symbol mL or ml) is a unit of volume that is used in the metric system. It is defined as one thousandth of a liter, or the volume of a cube with sides of 1 millimeter (0.001 meter) in length.

One milliliter is equal to 1 cubic centimeter, 0.000001 cubic meters, or 0.001 cubic decimeters.

History of the Milliliter

The milliliter is derived from the liter, which is a unit of volume that was first used by the French chemist Antoine Lavoisier in 1795 as a unit of volume for liquids and gases. The liter was originally defined as the volume of one kilogram of pure water at 4 °C and standard atmospheric pressure. The liter was later redefined several times based on different physical standards, such as a platinum-iridium cylinder and a wavelength of light. The current definition of the liter, adopted in 1964, is based on the cubic meter, which is the SI unit of volume. The liter is not an SI unit, but it is accepted by the CGPM (the standards body that defines the SI) for use with the SI.

The milliliter was introduced as a subunit of the liter in the metric system in 1795, along with other decimal subunits such as the centiliter and the deciliter. The milliliter was used for measuring very small volumes of liquids and gases, such as medicine, perfume, ink, and blood. The milliliter was also used for measuring some solids, such as granulated sugar, salt, and flour. The milliliter was adopted as a standard unit of measure in many countries that use the metric system, such as France, Germany, Italy, Spain, and Sweden.

How to Convert Milliliters

To convert milliliters to other units of volume, you need to multiply or divide by the appropriate conversion factor. Here are some common conversion factors and examples:

• To convert milliliters to cubic centimeters, multiply by 1.
  • Example: 2 mL × 1 = 2 cm3
• To convert milliliters to cubic meters, multiply by 0.000001.
  • Example: 2 mL × 0.000001 = 0.000002 m3
• To convert milliliters to cubic decimeters, multiply by 0.001.
  • Example: 2 mL × 0.001 = 0.002 dm3
• To convert milliliters to gallons (US liquid), multiply by 0.000264.
  • Example: 2 mL × 0.000264 = 0.000528 gal
• To convert milliliters to bushels (US), multiply by 0.0000374.
  • Example: 2 mL × 0.0000374 = 0.0000748 bu
• To convert milliliters to barrels (oil), multiply by 0.0000063.
  • Example: 2 mL × 0.0000063 = 0.0000126 bbl

To convert other units of volume to milliliters, you need to divide by the appropriate conversion factor. Here are some common conversion factors and examples:

• To convert cubic centimeters to milliliters, divide by 1.
  • Example: 2 cm3 ÷ 1 = 2 mL
• To convert cubic meters to milliliters, divide by 0.000001.
  • Example: 0.000002 m3 ÷ 0.000001 = 2 mL
• To convert cubic decimeters to milliliters, divide by 0.001.
  • Example: 0.002 dm3 ÷ 0.001 = 2 mL
• To convert gallons (US liquid) to milliliters, divide by 0.000264.
  • Example: 0.000528 gal ÷ 0.000264 = 2 mL
• To convert bushels (US) to milliliters, divide by 0.0000374.
  • Example: 0.0000748 bu ÷ 0.0000374 = 2 mL
• To convert barrels (oil) to milliliters, divide by 0.0000063.
  • Example: 0.0000126 bbl ÷ 0.0000063 = 2 mL

Where Milliliters are Used

Milliliters are used for measuring various materials and substances in different countries and applications.

Some examples are:
