Explanation

kilowatt-hours and megajoules are units of energy. They are used in common measurement contexts. Which one you use depends on the unit system or industry. They are defined at different scales, so the factor is not 1: 1 kilowatt-hours = 3.6 megajoules, and 1 megajoules = 0.2777777778 kilowatt-hours. Because one megajoules represents a smaller amount than one kilowatt-hours, the numeric value gets larger in this direction.

How to convert kilowatt-hours to megajoules

  1. Enter the value in kilowatt-hours (kWh).
  2. Multiply it by 3.6.
  3. The result is the equivalent value in megajoules (MJ).
  4. Round the result if needed.

Worked example

139160 × 3.6 = 500976 megajoules
