## Q. What is a Gigajoule ?

Answer: Gigajoule is SI derived multiple of the energy unit joule(J).

## Q. How much is 1 Gigajoule energy?

It is equal to 1.00E+09 times joules.

Symbol : GJ

So 1 gigajoule = 1.00E+09 joules.

Example Conversion: 510 gigajoule = 1.00E+09 X 510 joules.

Or we can say, 510 GJ = 510000000000 J.
