How to Convert Gigajoules to Joules

Convert gigajoules to joules with this simple formula:

joules = gigajoules × 1,000,000,000

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

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