How the formula works
Both nanojoule and zeptojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in nanojoules by 1000000000000 to get zeptojoules. To reverse the conversion, multiply a zeptojoule value by 1.000000000e-12 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 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.
How do I convert nanojoules to zeptojoules?
Multiply the nanojoule value by 1000000000000 to get the equivalent in zeptojoules. For example, 5 nJ × 1000000000000 = 5.000000e+12 zJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1000000000000 is an exact, non-rounded value.
Can I convert zeptojoules back to nanojoules?
Yes. Divide the zeptojoule value by 1000000000000, or multiply it by 1.000000000e-12, to get nanojoules.
