How the formula works
Both nanojoule and yoctojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in nanojoules by 1.000000000e+15 to get yoctojoules. To reverse the conversion, multiply a yoctojoule value by 1.000000000e-15 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 Yoctojoule (yJ)?
A yoctojoule (yJ) is a metric-prefixed unit of energy equal to 10-24 joules, a fraction of a single joule, using the SI yocto prefix.
How do I convert nanojoules to yoctojoules?
Multiply the nanojoule value by 1.000000000e+15 to get the equivalent in yoctojoules. For example, 5 nJ × 1.000000000e+15 = 5.000000e+15 yJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e+15 is an exact, non-rounded value.
Can I convert yoctojoules back to nanojoules?
Yes. Divide the yoctojoule value by 1.000000000e+15, or multiply it by 1.000000000e-15, to get nanojoules.
