One of many SI units of measure expressed as relationships of the SI base units. For example, the watt, W, is the SI derived unit of power. It is equal to joules per second. W = m2 ⋅ kg ⋅ s–3 (Note: the joule, J, is the SI derived unit for energy, work, or quantity of heat.) See also Units of Measure.

One of seven SI units of measure from which all the other SI units are derived. See SI derived unit.
