kWh to W Conversion Calculator Energy to Power Calculations

KWh to watts calculator:

The energy in kWh (kilo-Watt-Hour) in the first table and time in the hour in the second table and press calculate button to get the Power to result in watts.

Enter energy in kilowatt-hours: kWh
Enter time in hours: hr
   
Power result in watts: W

1000 times of kilowatts hour (kWh) divide by Time (t(hr)) is equal to Watt (W). Watt is the SI unit of power. Hence,

Power = 1000 * energy in kilowatt-hour / Time in hour

=> P(W) = 1000 × E(kWh) / t(hr)

Or in another word

W = 1000 * kWh / s(hr)

For Easy understanding,

A water heater consumes 500 kWh in a day, calculate the power in watt.

Power P(W) = 1000 * 500 / 24

P(W)  = 20833.33333 Watts
