How to Convert Gigajoules to Megajoules

Convert gigajoules to megajoules with this simple formula:

megajoules = gigajoules × 1,000

Converting a gigajoule energy measurement to a megajoule measurement involves multiplying the energy by the conversion ratio to find the result. One gigajoule is equal to 1,000 megajoules, so to convert simply multiply by 1,000.

For example:
5 GJ = (5 × 1,000) = 5,000 MJ
