Electricity-only EUI calculator

Convert delivered kWh to Btu before dividing by area; label the result electricity-only when other fuels are excluded.

Units

\mathrm{EUI}_{e} = \frac{3412 \times E_{e}}{A}

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Given

\mathrm{EUI}_{e} = \frac{3412 \times 180{,}000}{12{,}000} = 51{,}180
