How it works

Average power (W) = kWh × 1000 ÷ hours. Average current (A) = power ÷ (volts × power factor). This is the average over the period, not the peak.

Frequently asked questions

Why do I need the time?

kWh is total energy, not current. To get amps you must spread that energy over a time to find the average power, then divide by voltage.

What voltage should I use?

Your local mains voltage — about 120 V in North America, 230 V in Europe and the UK.

Is this peak or average current?

Average. Real draw rises and falls; this gives the steady-average figure over the chosen time.
