The base quantities used in the International System of Units are length, mass, time, electric current, thermodynamic temperature, amount of substance, and luminous intensity. The corresponding base units of the SI were chosen by the CGPM to be the metre, the kilogram, the second, the ampere, the kelvin, the mole, and the candela.
The International System of Units (SI) specifies a set of seven base units from which all other SI units of measurement are derived. These SI derived units are either dimensionless, or can be expressed as a product of one or more of the base units, possibly scaled by an appropriate power of exponentiation. Many derived units do not have special names. For example, the SI derived unit of area is the square metre (m2) and the SI derived unit of density is the kilogram per cubic metre (kg/m3 or kg mâ3). However, 22 derived units are recognized by the SI with special names, which are written in lowercase.
