How the formula works
Both ronnajoule and erg measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in ronnajoules by 1.000000000e+34 to get ergs. To reverse the conversion, multiply a erg value by 1.000000000e-34 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 Erg (erg)?
An erg is the CGS (centimeter-gram-second) unit of energy, equal to one ten-millionth of a joule.
How do I convert ronnajoules to ergs?
Multiply the ronnajoule value by 1.000000000e+34 to get the equivalent in ergs. For example, 5 RJ × 1.000000000e+34 = 5.000000e+34 erg.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e+34 is an exact, non-rounded value.
Can I convert ergs back to ronnajoules?
Yes. Divide the erg value by 1.000000000e+34, or multiply it by 1.000000000e-34, to get ronnajoules.
