kilogram (kg), basic unit of mass in the metric system. A kilogram is very nearly equal (it was originally intended to be exactly equal) to the mass of 1,000 cubic cm of water. The standard kilogram was kept at the International Bureau of Weights and Measures laboratory at Sèvres, France.
What is the kilogram standard made of?

kilogram
The SI unit of mass is the kilogram (kg).
What is the standard unit of weight?
The unit of measurement for weight is that of force, which in the International System of Units (SI) is the newton. For example, an object with a mass of one kilogram has a weight of about 9.8 newtons on the surface of the Earth, and about one-sixth as much on the Moon.
What replaced Le Grand K?
Scientists had to do something, so they turned to… science, of course. In November, hundreds of scientists gathered for the 26th General Conference on Weights and Measures and voted to replace Le Grand K with a universal formula that defines the kilogram with the quantum laws of nature.
What was the original kilogram based on?
The kilogram was originally defined in 1795 as the mass of one litre of water.
What is the standard unit of measurement that French created called?
In 1790, the French created a standard unit of measurement called the metric system. SI unit of length is metre (m) while for large distances; the unit is kilometer (km).
How does France measure height?
Today, the metric system, which was created in France, is the official system of measurement for every country in the world except three: the United States, Liberia and Myanmar, also known as Burma. And even then, the metric system is still used for purposes such as global trade.

What happened to the original French prototype of the kilogram?
More than a century of cleanings and exposure to air had caused the original French prototype — known as the International Prototype of the Kilogram, or “Le Grand K” — to lose about 50 micrograms. That’s roughly the mass contained within a handful of fingerprints.
What was the original definition of a kilogram?
The kilogram was originally defined in 1795 as the mass of one litre of water. Modern superseding definitions of a kilogram agree with this original definition to within 30 parts per million. In 1799, the platinum Kilogramme des Archives replaced it as the standard of mass.
How many countries voted to redefine the kilogram?
The vote to redefine the kilogram was, as expected, unanimous, with representatives from more than 50 countries saying “yes” or “oui” at the historic meeting in Versailles, France.
