Explanation

megajoules and gigajoules 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 = 0.001 gigajoules, and 1 gigajoules = 1000 megajoules. Because one gigajoules represents a larger amount than one megajoules, the numeric value gets smaller in this direction.

How to convert megajoules to gigajoules

  1. Enter the value in megajoules (MJ).
  2. Multiply it by 0.001.
  3. The result is the equivalent value in gigajoules (GJ).
  4. Round the result if needed.

Worked example

28992 × 0.001 = 28.992 gigajoules

Frequently Asked Questions
