About these units

Kilograms

History
The kilogram was originally defined in 1799 as the mass of one liter of water. It was the last SI base unit to be defined by a physical artifact (the IPK in Paris) — replaced by a fundamental-constant definition in 2019.
Current use
The kilogram is the standard unit of mass for science, commerce, and everyday use in every country except the United States.
