Concept Card: Dimensions of Physical Quantities & Dimensional Formulae 1. Definition of Dimensions: The dimensions of a physical quantity are the powers (or exponents) to which the fundamental base quantities must be raised to represent that quantity. The standard dimensional expression is represented in terms of the seven base dimensions: $[Q] = [M^a L^b T^c … Read more
