; Dimensions of quantities
;
; By convention physical quantities are organized in a system of dimensions.
; Each of the seven base quantities used in the SI is regarded as having its
; own dimension.

; SI base units
;
; Every base SI unit relates the base quantity to the unit symbol and
; optional unit name(s).

; SI derived units
;
; Derived units are products of powers of base units.
; Derived units expressed in terms of base units do not need to be defined.
