How the formula works
Both picojoule and rontojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in picojoules by 1.000000000e+15 to get rontojoules. To reverse the conversion, multiply a rontojoule value by 1.000000000e-15 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 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 picojoules to rontojoules?
Multiply the picojoule value by 1.000000000e+15 to get the equivalent in rontojoules. For example, 5 pJ × 1.000000000e+15 = 5.000000e+15 rJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e+15 is an exact, non-rounded value.
Can I convert rontojoules back to picojoules?
Yes. Divide the rontojoule value by 1.000000000e+15, or multiply it by 1.000000000e-15, to get picojoules.
