How the formula works
Both ronnajoule and joule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in ronnajoules by 1.000000000e+27 to get joules. To reverse the conversion, multiply a joule value by 1.000000000e-27 to get back to ronnajoules.
Frequently asked questions
What is Ronnajoule (RJ)?
A ronnajoule (RJ) is a metric-prefixed unit of energy equal to 1027 joules, using the SI ronna prefix.
What is Joule (J)?
The joule (J) is the SI derived unit of energy, equal to the work done when a force of one newton acts over one meter.
How do I convert ronnajoules to joules?
Multiply the ronnajoule value by 1.000000000e+27 to get the equivalent in joules. For example, 5 RJ × 1.000000000e+27 = 5.000000e+27 J.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e+27 is an exact, non-rounded value.
Can I convert joules back to ronnajoules?
Yes. Divide the joule value by 1.000000000e+27, or multiply it by 1.000000000e-27, to get ronnajoules.
