Kilogram

The kilogram (kg) is the unit of mass (m). The name is derived from the Greek words kilo (κιλό), meaning "thousand", and gramma (γράμμα), known in the Late Antiquity as 1/24 part of a Roman uncia or about 1.14 gram.

The kilogram is defined in terms of second and meter, based on fixed fundamental constants of nature.
