An expression showing the powers to which the fundamental quantities are to be raised to represent the derived quantity is called dimensional formula of that quantity.
In general the dimensional formula of a quantity can be written as $$ \left[\mathbf{M}^{2} \mathbf{H} \mathbf{T}^{z}\right] . $$ Here $$ \mathbf{x}, y, z $$ are dimensions.
