The dimensional formula for inductance is 

Equation involving inductance

Energy stored in an inductance 

$\mathrm{U}=\frac{1}{2}{\mathrm{Li}}^2$

$\mathrm{Inductance} \mathrm{L}=\frac{2\mathrm{U}}{{\mathrm{i}}^2}$

$\mathrm{dimensional} \mathrm{formula} =\frac{{\mathrm{ML}}^2{\mathrm{T}}^{-2}}{{\mathrm{A}}^2}={\mathrm{ML}}^2{\mathrm{T}}^{-2}{\mathrm{A}}^2$
