How the formula works
Both nanojoule and terajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in nanojoules by 1.000000000e-21 to get terajoules. To reverse the conversion, multiply a terajoule value by 1.000000000e+21 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 Terajoule (TJ)?
A terajoule (TJ) is a metric-prefixed unit of energy equal to 1012 joules, using the SI tera prefix.
How do I convert nanojoules to terajoules?
Multiply the nanojoule value by 1.000000000e-21 to get the equivalent in terajoules. For example, 5 nJ × 1.000000000e-21 = 5.000000e-21 TJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-21 is an exact, non-rounded value.
Can I convert terajoules back to nanojoules?
Yes. Divide the terajoule value by 1.000000000e-21, or multiply it by 1.000000000e+21, to get nanojoules.
