How the formula works
Both picojoule and exajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in picojoules by 1.000000000e-30 to get exajoules. To reverse the conversion, multiply a exajoule value by 1.000000000e+30 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 Exajoule (EJ)?
A exajoule (EJ) is a metric-prefixed unit of energy equal to 1018 joules, using the SI exa prefix.
How do I convert picojoules to exajoules?
Multiply the picojoule value by 1.000000000e-30 to get the equivalent in exajoules. For example, 5 pJ × 1.000000000e-30 = 5.000000e-30 EJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-30 is an exact, non-rounded value.
Can I convert exajoules back to picojoules?
Yes. Divide the exajoule value by 1.000000000e-30, or multiply it by 1.000000000e+30, to get picojoules.
