Dimension equation is a mathematical equation that can be used to express the dimensions of a mathematical sum. The dimension equations in terms of quantities can be as follows: force , [F] = [MLT − 2] work , [W] = [ML2T − 2] power , [p] = [ML2T − 3] power , [E] = [ML2T− 2] Density , [ρ] = [ML − 3] pressure , [p] = [ML − 1T − 2] heat , [Q] = [ML2T − 2] heat capacity , [C] = [ML2T − 2θ− 1]
