How to Convert Kilowatt Hours to Megajoules
- 1). Multiply the number of kWh by 3.6 MJ per kWh to convert to MJ. For example, if you had 8 kWh, you would multiply 8 kWh by 3.6 MJ per kWh to get 28.8 MJ.
- 2). Divide the number of kWh by 0.277778 MJ per kWh to check your conversion to MJ. In this example, you would divide 8 kWh by 0.277778 MJ per kWh to get 28.8 MJ.
- 3). Confirm your answer using an online calculator (see Resources).
