How the formula works
Both nanojoule and quettajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in nanojoules by 1.000000000e-39 to get quettajoules. To reverse the conversion, multiply a quettajoule value by 1.000000000e+39 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 Quettajoule (QJ)?
A quettajoule (QJ) is a metric-prefixed unit of energy equal to 1030 joules, using the SI quetta prefix.
How do I convert nanojoules to quettajoules?
Multiply the nanojoule value by 1.000000000e-39 to get the equivalent in quettajoules. For example, 5 nJ × 1.000000000e-39 = 5.000000e-39 QJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-39 is an exact, non-rounded value.
Can I convert quettajoules back to nanojoules?
Yes. Divide the quettajoule value by 1.000000000e-39, or multiply it by 1.000000000e+39, to get nanojoules.
