KW to kWh Calculation Theory

To calculate the energy E in kiloWatt-hours (kWh), multiply the power P in kiloWatts (kW) by the time period t in hours (h).

Equation to calculate energy in kilowatt-hours (kWh)

KW to kiloWatt-hours Calculation Example

To calculate how much energy you use in your home, you need to know the power rating of your appliances in kilowatts (kW) and how long you use them for in hours (h). For example, if you have a 1 kW toaster and you use it for 30 minutes (0.5 hours), the energy used is:

E = P x t = 1 kW x 0.5 h = 0.5 kWh

So, using the toaster for 30 minutes uses 0.5 kiloWatt-hours of energy.
