base unit

Physics

A unit that is defined arbitrarily rather than being defined by simple combinations of other units. For example, the ampere is a base unit in the SI system defined in terms of the force produced between two current-carrying conductors, whereas the coulomb is a derived unit, defined as the quantity of charge transferred by one ampere in one second.

Mathematics

See SI units.

Chemistry

A unit that is defined arbitrarily rather than being defined by simple combinations of other units. For example, the ampere is a base unit in the SI system defined in terms of the force produced between two current-carrying conductors, whereas the coulomb is a derived unit, defined as the quantity of charge transferred by one ampere in one second.

Chemical Engineering

A unit that is defined arbitrarily and not related in combination with other units. In the SI system, there are seven base units: kilogram (kg) for mass, metre (m) for length, second (s) for time, kelvin (K) for temperature, mole (mol) for the amount of substance, ampere (A) for electrical current, and candela (cd) for luminous intensity. Derived units are defined as combinations of base units such the newton (N) which is a unit of force where 1 N is equal to 1 kg m s⁻².
