i have a kiln. it uses 240 volts, 48 amps. how many kWh are used for every 1hr of use? thank you for your help...

240 V * 48 A = 11520 W = 11.52 kW
Thus, in an hour, it uses 11.52 kWh

Re: how to convert amps into kwh usage

If a electric unit uses 30A/120V,
what is the actual kwh usage?.

30 A * 120 V = 4800 W or 4.8 kW
Every hour, it uses 4.8 kWh
