Explanation

megajoules and joules 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 megajoules = 1000000 joules, and 1 joules = 0.000001 megajoules. Because one joules represents a smaller amount than one megajoules, the numeric value gets larger in this direction.

How to convert megajoules to joules

  1. Enter the value in megajoules (MJ).
  2. Multiply it by 1000000.
  3. The result is the equivalent value in joules (J).
  4. Round the result if needed.

Worked example

5142 × 1000000 = 5.14200000e+9 joules
