How the formula works
Both picojoule and ronnajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in picojoules by 1.000000000e-39 to get ronnajoules. To reverse the conversion, multiply a ronnajoule value by 1.000000000e+39 to get back to picojoules.
Frequently asked questions
What is Picojoule (pJ)?
A picojoule (pJ) is a metric-prefixed unit of energy equal to 10-12 joules, a fraction of a single joule, using the SI pico prefix.
What is Ronnajoule (RJ)?
A ronnajoule (RJ) is a metric-prefixed unit of energy equal to 1027 joules, using the SI ronna prefix.
How do I convert picojoules to ronnajoules?
Multiply the picojoule value by 1.000000000e-39 to get the equivalent in ronnajoules. For example, 5 pJ × 1.000000000e-39 = 5.000000e-39 RJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-39 is an exact, non-rounded value.
Can I convert ronnajoules back to picojoules?
Yes. Divide the ronnajoule value by 1.000000000e-39, or multiply it by 1.000000000e+39, to get picojoules.
