Answer:
Kilogram:
The fundamental mass unit in the metric system is the kilograms (kg). The mass of 1,000 cubic centimeters of water is very close to (and was originally intended to be exactly) one kilograms. The actual weight of a pound is 0.45359237 kg.
Explanation:
The standard international (SI) system of units uses the kilograms as its unit of mass. It is described as being the mass of a certain platinum-iridium prototype that is held at the International Bureau of Weights and Measures. One liter of pure water's bulk (10-3 cubic meters) served as its original definition.
The SI unit of mass is known as the kilograms, or kg. The Planck constant h is taken to have a fixed value of 6.626070151034 when represented in the unit Js, which is equivalent to kgm2s1, with the meter and the second being defined in terms of c and vCs.
