How the formula works
Both exajoule and rontojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in exajoules by 1.000000000e+45 to get rontojoules. To reverse the conversion, multiply a rontojoule value by 1.000000000e-45 to get back to exajoules.
Frequently asked questions
What is Exajoule (EJ)?
A exajoule (EJ) is a metric-prefixed unit of energy equal to 1018 joules, using the SI exa 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 exajoules to rontojoules?
Multiply the exajoule value by 1.000000000e+45 to get the equivalent in rontojoules. For example, 5 EJ × 1.000000000e+45 = 5.000000e+45 rJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e+45 is an exact, non-rounded value.
Can I convert rontojoules back to exajoules?
Yes. Divide the rontojoule value by 1.000000000e+45, or multiply it by 1.000000000e-45, to get exajoules.
