How the formula works
Both zeptojoule and nanojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in zeptojoules by 1.000000000e-12 to get nanojoules. To reverse the conversion, multiply a nanojoule value by 1000000000000 to get back to zeptojoules.
Frequently asked questions
What is Zeptojoule (zJ)?
A zeptojoule (zJ) is a metric-prefixed unit of energy equal to 10-21 joules, a fraction of a single joule, using the SI zepto prefix.
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.
How do I convert zeptojoules to nanojoules?
Multiply the zeptojoule value by 1.000000000e-12 to get the equivalent in nanojoules. For example, 5 zJ × 1.000000000e-12 = 5.000000e-12 nJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-12 is an exact, non-rounded value.
Can I convert nanojoules back to zeptojoules?
Yes. Divide the nanojoule value by 1.000000000e-12, or multiply it by 1000000000000, to get zeptojoules.
