Watts (W) to kilowatthours (kWh) The energy E in kilowatthours (kWh) is equal to the power P in watts (W), times the time period t in hours (hr) divided by 1000: E_{(kWh)} = P_{(W)} x t_{(hr)} / 1000 

Enter the power in watts, consumption time period in hours  


Power in watts (W) to energy in kilowatthours (kWh) calculator and calculation formula.  
How to convert 
A kilowatthour, expressed as kWh or kW·h, is a measure of energy that is equivalent to 1,000 watts of power for a 1hour time period. Thus, to convert watts to kilowatthours, multiply the power in watts by the number of hours, then divide by 1,000.
