How the formula works
Both picojoule and erg measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in picojoules by 0.00001 to get ergs. To reverse the conversion, multiply a erg value by 100000 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 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 picojoules to ergs?
Multiply the picojoule value by 0.00001 to get the equivalent in ergs. For example, 5 pJ × 0.00001 = 0.000050 erg.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 0.00001 is an exact, non-rounded value.
Can I convert ergs back to picojoules?
Yes. Divide the erg value by 0.00001, or multiply it by 100000, to get picojoules.
