## kW to kJ calculation formula

E_{(kJ)} = P_{(kW)} × t_{(s)}

The energy **E** in kilojoules (kJ) is equal to the power **P** in kilowatts (kW), multiplied by the time period **t** in seconds (s).

So,

*kJ = kW x s*

*kilojoule = kilowatt x second*

**For example:**

*Power (P) = 2,5kW*

*Time period = 5 seconds*

*Energy (E) = 2,5kW x 5s = 12,5kJ*
