How the formula works
Both nanojoule and erg measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in nanojoules by 0.01 to get ergs. To reverse the conversion, multiply a erg value by 100 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 Erg (erg)?
An erg is the CGS (centimeter-gram-second) unit of energy, equal to one ten-millionth of a joule.
How do I convert nanojoules to ergs?
Multiply the nanojoule value by 0.01 to get the equivalent in ergs. For example, 5 nJ × 0.01 = 0.050000 erg.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 0.01 is an exact, non-rounded value.
Can I convert ergs back to nanojoules?
Yes. Divide the erg value by 0.01, or multiply it by 100, to get nanojoules.
