Dimensional formula of capacitance is
$ {M^{ - 1}}{L^{ - 2}}{T^4}{A^2}$
$M{L^2}{T^4}{A^{ - 2}}$
$ML{T^{ - 4}}{A^2}$
${M^{ - 1}}{L^{ - 2}}{T^{ - 4}}{A^{ - 2}}$
Dimensional formula of capacitance is
$[C] =$ $\left( {\frac{Q}{V}} \right) $ $ = \left( {\frac{{{Q^2}}}{W}} \right) $ $= \left[ {\frac{{{A^2}{T^2}}}{{M{L^2}{T^{ - 2}}}}} \right]$ $ = [{M^{ - 1}}{L^{ - 2}}{T^4}{A^2}]$
