How the formula works
Both picojoule and yoctojoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in picojoules by 1000000000000 to get yoctojoules. To reverse the conversion, multiply a yoctojoule value by 1.000000000e-12 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 Yoctojoule (yJ)?
A yoctojoule (yJ) is a metric-prefixed unit of energy equal to 10-24 joules, a fraction of a single joule, using the SI yocto prefix.
How do I convert picojoules to yoctojoules?
Multiply the picojoule value by 1000000000000 to get the equivalent in yoctojoules. For example, 5 pJ × 1000000000000 = 5.000000e+12 yJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1000000000000 is an exact, non-rounded value.
Can I convert yoctojoules back to picojoules?
Yes. Divide the yoctojoule value by 1000000000000, or multiply it by 1.000000000e-12, to get picojoules.
