kWh: definition and calculation method

  • The kilowatthour (kWh) is a unit that measures energy.
  • One kWh is equal to the consumption of one 1,000-watt electronic device in one hour.

To calculate the consumption of a device, multiply its power by the number of hours of use. Then, divide the result by 1,000 to obtain the consumption in kWh.
