KWh to watts calculator

Use this tool to convert energy measured in kilowatt-hours (kWh) to power in watts (W) with our easy-to-use formula.

Simply input the energy in kilowatt-hours and the duration in hours, then hit the 'Calculate' button to get your results.

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

Calculating KWh to Watts: To determine the power P in watts (W) from energy E in kilowatt-hours (kWh), multiply the energy by 1000 and then divide by the duration t in hours (hr):

P(W) = 1000 × E(kWh) / t(hr)

Understanding the Basics:

  • Kilowatt-hours (kWh): Represents energy consumption.
  • Watts (W): Indicates the rate of power or energy use.

How It Works: By inputting the energy value in kWh and the time duration in hours, users can effortlessly determine the corresponding power in watts. The underlying formula is: P(W) = 1000 × E(kWh) / t(hr).


  • Efficiency: Eliminates manual calculations, saving time.
  • Accuracy: Reduces potential errors in conversions.
  • Versatility: Useful for professionals, students, and anyone keen on understanding energy metrics.

The KWh to Watts calculator is an essential tool for all who deal with energy and power dynamics, bridging the gap between complex concepts and everyday applications.
