How the formula works
Both nanojoule and petajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in nanojoules by 1.000000000e-24 to get petajoules. To reverse the conversion, multiply a petajoule value by 1.000000000e+24 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 Petajoule (PJ)?
A petajoule (PJ) is a metric-prefixed unit of energy equal to 1015 joules, using the SI peta prefix.
How do I convert nanojoules to petajoules?
Multiply the nanojoule value by 1.000000000e-24 to get the equivalent in petajoules. For example, 5 nJ × 1.000000000e-24 = 5.000000e-24 PJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-24 is an exact, non-rounded value.
Can I convert petajoules back to nanojoules?
Yes. Divide the petajoule value by 1.000000000e-24, or multiply it by 1.000000000e+24, to get nanojoules.
