kg redirects here. For other uses, see KG. The kilogram or kilogramme (SI unit symbol: kg) is the base unit of mass in the International System of Units (SI) (the Metric system) and is defined as being equal to the mass of the International Prototype of the Kilogram (IPK, also known as Le Grand K or Big K).
Density is the mass of air molecules per unit volume. Mass is measured by the kilogram (kg), and volume in cubic metres (m 3), so the unit of density is kilograms per cubic metre (kg m -3). We think of kilograms in terms of weight, but weight is the result of a mass subjected to gravity.
