How the formula works
Both nanojoule and rontojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in nanojoules by 1.000000000e+18 to get rontojoules. To reverse the conversion, multiply a rontojoule value by 1.000000000e-18 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 Rontojoule (rJ)?
A rontojoule (rJ) is a metric-prefixed unit of energy equal to 10-27 joules, a fraction of a single joule, using the SI ronto prefix.
How do I convert nanojoules to rontojoules?
Multiply the nanojoule value by 1.000000000e+18 to get the equivalent in rontojoules. For example, 5 nJ × 1.000000000e+18 = 5.000000e+18 rJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e+18 is an exact, non-rounded value.
Can I convert rontojoules back to nanojoules?
Yes. Divide the rontojoule value by 1.000000000e+18, or multiply it by 1.000000000e-18, to get nanojoules.
