## Q. What is a Zeptojoule ?

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

## Q. How much is 1 Zeptojoule energy?

It is equal to 1.00E-21 times joules.

Symbol : zJ

So 1 zeptojoule = 1.00E-21 joules.

Example Conversion: 650 zeptojoule = 1.00E-21 X 650 joules.

Or we can say, 650 zJ = 6.5E-19 J.
