How the formula works
Both attojoule and rontojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in attojoules by 1000000000 to get rontojoules. To reverse the conversion, multiply a rontojoule value by 1.000000000e-09 to get back to attojoules.
Frequently asked questions
What is Attojoule (aJ)?
A attojoule (aJ) is a metric-prefixed unit of energy equal to 10-18 joules, a fraction of a single joule, using the SI atto 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 attojoules to rontojoules?
Multiply the attojoule value by 1000000000 to get the equivalent in rontojoules. For example, 5 aJ × 1000000000 = 5.000000e+09 rJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1000000000 is an exact, non-rounded value.
Can I convert rontojoules back to attojoules?
Yes. Divide the rontojoule value by 1000000000, or multiply it by 1.000000000e-09, to get attojoules.
