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