How to Convert Gigajoules to Kilojoules

Convert gigajoules to kilojoules with this simple formula:

kilojoules = gigajoules × 1,000,000

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

For example:

5 GJ = (5 × 1,000,000) = 5,000,000 kJ

Gigajoules and kilojoules are both units used to measure energy. Learn more about energy and find more energy measurement conversion calculators. Gigajoules are an SI derived unit of energy and can be abbreviated as GJ, for example 1 GJ. Kilojoules are an SI derived unit of energy and can be abbreviated as kJ, for example 1 kJ.
