Equivalent full-load operating hours calculator

Divide measured energy by the stated power; the result is actual runtime only if that power remained constant while running.

h_{\text{eq}} = \frac{E}{P}

Calculator

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

Given

h_{\text{eq}} = \frac{96}{12} = 8

Symbol	Meaning	Unit
$h_{\text{eq}}$	equivalent operating duration at the stated power	h
$E$	metered energy over the period	kWh
$P$	stated constant or reference real power	kW

Results are estimates for study and screening. Check the inputs, units and assumptions before you use them for design, billing or contract decisions.
