Thus the units of volume will be m 3 (in the SI) or cm 3, ft 3 (English), etc. Moreover, any formula that calculates a volume must contain within it the L 3 dimension; thus the volume of a sphere is \(4/3 πr^3\). The dimensions of a unit are the powers which M, L, t, Q and Q must be given in order to express the unit. Thus, \[dim\{V\} = M^0L Unit conversions only work if the units are the same type.
