How the formula works
Both exajoule and microjoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in exajoules by 1.000000000e+24 to get microjoules. To reverse the conversion, multiply a microjoule value by 1.000000000e-24 to get back to exajoules.
Frequently asked questions
What is Exajoule (EJ)?
A exajoule (EJ) is a metric-prefixed unit of energy equal to 1018 joules, using the SI exa 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 exajoules to microjoules?
Multiply the exajoule value by 1.000000000e+24 to get the equivalent in microjoules. For example, 5 EJ × 1.000000000e+24 = 5.000000e+24 uJ.
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 microjoules back to exajoules?
Yes. Divide the microjoule value by 1.000000000e+24, or multiply it by 1.000000000e-24, to get exajoules.
