How the formula works
Both picojoule and microjoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in picojoules by 0.000001 to get microjoules. To reverse the conversion, multiply a microjoule value by 1000000 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 Microjoule (uJ)?
A microjoule (uJ) is a metric-prefixed unit of energy equal to 10-6 joules, a fraction of a single joule, using the SI micro prefix.
How do I convert picojoules to microjoules?
Multiply the picojoule value by 0.000001 to get the equivalent in microjoules. For example, 5 pJ × 0.000001 = 0.000005 uJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 0.000001 is an exact, non-rounded value.
Can I convert microjoules back to picojoules?
Yes. Divide the microjoule value by 0.000001, or multiply it by 1000000, to get picojoules.
