## kW to kWh calculation formula

E_{(kWh)} = P_{(kW)} × t_{(h)}

The energy **E** in kilowatt-hours (kWh) is equal to the power **P** in kilowatts (kW), multiplied by the time period **t** in hours (h).

So,

*kWh = kW x h*

*kilowatt-hour = kilowatt x hour*

**For example:**

*Power (P) = 10kW*

*Time period = 2 hours*

*Energy (E) = 10kW x 2h = 20kWh*
