How to Convert Megajoules to Joules

Convert megajoules to joules with this simple formula:

joules = megajoules × 1,000,000

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

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

Megajoules and joules are both units used to measure energy. Learn more about energy and find more energy measurement conversion calculators. Megajoules are an SI derived unit of energy and can be abbreviated as MJ, for example 1 MJ. Joules are an SI derived unit of energy and can be abbreviated as J, for example 1 J.
