How the formula works
Both attojoule and nanojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attojoules by 1.000000000e-09 to get nanojoules. To reverse the conversion, multiply a nanojoule value by 1000000000 to get back to attojoules.
Frequently asked questions
What is Attojoule (aJ)?
A attojoule (aJ) is a metric-prefixed unit of energy equal to 10-18 joules, a fraction of a single joule, using the SI atto prefix.
What is Nanojoule (nJ)?
A nanojoule (nJ) is a metric-prefixed unit of energy equal to 10-9 joules, a fraction of a single joule, using the SI nano prefix.
How do I convert attojoules to nanojoules?
Multiply the attojoule value by 1.000000000e-09 to get the equivalent in nanojoules. For example, 5 aJ × 1.000000000e-09 = 5.000000e-09 nJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-09 is an exact, non-rounded value.
Can I convert nanojoules back to attojoules?
Yes. Divide the nanojoule value by 1.000000000e-09, or multiply it by 1000000000, to get attojoules.
