WebEach variant of the metric system has a degree of coherence – the various derived units being directly related to the base units without the need of intermediate conversion factors. [1] An additional criterion is that, for example, in a coherent system the units of force, energy and power be chosen so that the equations WebThe derived units either lack dimension or are the products of the base units. For example, the derived unit of force is Newton (N). SYMBOLS AND NAMES OF DERIVED UNIT. Lowercase is used for all derived unit names. In general, the names are combinations of the base units, but there are 22 derived units with special names.

WebSI derived units Other quantities, called derived quantities, are defined in terms of the seven base quantities via a system of quantity equations. The SI derived units for these derived quantities are obtained from these equations and the seven SI base units.
