Definition: A kilogram (symbol: kg) is the base unit of mass in the International System of Units (SI).

Originally defined as the mass of one liter of water at its freezing point, the kilogram is now defined in terms of the Planck constant. Since 2019, it has been defined by setting the value of the Planck constant exactly to 6.62607015×10⁻³⁴ joule-second.

The kilogram is used globally in nearly all fields and applications, with the exception of countries like the United States, where the pound is still commonly used for certain measurements.
