How the formula works
Both nanojoule and femtojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in nanojoules by 1000000 to get femtojoules. To reverse the conversion, multiply a femtojoule value by 0.000001 to get back to nanojoules.
Frequently asked questions
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.
What is Femtojoule (fJ)?
A femtojoule (fJ) is a metric-prefixed unit of energy equal to 10-15 joules, a fraction of a single joule, using the SI femto prefix.
How do I convert nanojoules to femtojoules?
Multiply the nanojoule value by 1000000 to get the equivalent in femtojoules. For example, 5 nJ × 1000000 = 5.000000e+06 fJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1000000 is an exact, non-rounded value.
Can I convert femtojoules back to nanojoules?
Yes. Divide the femtojoule value by 1000000, or multiply it by 0.000001, to get nanojoules.
