## Q. What is a Attojoule ?

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

## Q. How much is 1 Attojoule energy?

It is equal to 1.00E-18 times joules.

Symbol : aJ

So 1 attojoule = 1.00E-18 joules.

Example Conversion: 389 attojoule = 1.00E-18 X 389 joules.

Or we can say, 389 aJ = 3.89E-16 J.
