Essentials of the SI: Base & derived units - NIST
WEBFor detailed information on the SI base units, see Definitions of the SI base units and their Historical context. SI derived units. Other quantities, called derived quantities, are defined in terms of the seven base quantities via a system of quantity equations.
SI derived unit - Wikipedia
WEBSI derived units are units of measurement derived from the seven SI base units specified by the International System of Units (SI). They can be expressed as a product (or ratio) of one or more of the base units, possibly scaled by an appropriate power of exponentiation (see: Buckingham π theorem).
