How the formula works
Both microjoule and exajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in microjoules by 1.000000000e-24 to get exajoules. To reverse the conversion, multiply a exajoule value by 1.000000000e+24 to get back to microjoules.
Frequently asked questions
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.
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 microjoules to exajoules?
Multiply the microjoule value by 1.000000000e-24 to get the equivalent in exajoules. For example, 5 uJ × 1.000000000e-24 = 5.000000e-24 EJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-24 is an exact, non-rounded value.
Can I convert exajoules back to microjoules?
Yes. Divide the exajoule value by 1.000000000e-24, or multiply it by 1.000000000e+24, to get microjoules.
