The Formula used in kW to kWh Conversion

The formula for converting kilowatts (kW) to kilowatt-hours (kWh) is:

kWh = Power (kW) X Time (hours)


  • Energy (kWh) is the energy consumption in kilowatt-hours (kWh).
  • Power (kW) is the power in kilowatts (kW).
  • Time (hours) is the time duration in hours.

This formula calculates the total energy consumed over a given time period when a certain power level is maintained consistently. It's commonly used in billing and monitoring energy consumption for various electrical appliances and systems.
