Defn: The manifoldness with which the fundamental units of time, length, and mass are involved in determining the units of other physical quantities. Thus, since the unit of velocity varies directly as the unit of length and inversely as the unit of time, the dimensions of velocity are said to be length ÷ time; the dimensions of work are mass × (length)2 ÷ (time)2; the dimensions of density are mass ÷ (length)3.
