How the formula works
Both nanojoule and quectojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in nanojoules by 1.000000000e+21 to get quectojoules. To reverse the conversion, multiply a quectojoule value by 1.000000000e-21 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 Quectojoule (qJ)?
A quectojoule (qJ) is a metric-prefixed unit of energy equal to 10-30 joules, a fraction of a single joule, using the SI quecto prefix.
How do I convert nanojoules to quectojoules?
Multiply the nanojoule value by 1.000000000e+21 to get the equivalent in quectojoules. For example, 5 nJ × 1.000000000e+21 = 5.000000e+21 qJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e+21 is an exact, non-rounded value.
Can I convert quectojoules back to nanojoules?
Yes. Divide the quectojoule value by 1.000000000e+21, or multiply it by 1.000000000e-21, to get nanojoules.
