How the formula works
Both microjoule and quettajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in microjoules by 1.000000000e-36 to get quettajoules. To reverse the conversion, multiply a quettajoule value by 1.000000000e+36 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 Quettajoule (QJ)?
A quettajoule (QJ) is a metric-prefixed unit of energy equal to 1030 joules, using the SI quetta prefix.
How do I convert microjoules to quettajoules?
Multiply the microjoule value by 1.000000000e-36 to get the equivalent in quettajoules. For example, 5 uJ × 1.000000000e-36 = 5.000000e-36 QJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-36 is an exact, non-rounded value.
Can I convert quettajoules back to microjoules?
Yes. Divide the quettajoule value by 1.000000000e-36, or multiply it by 1.000000000e+36, to get microjoules.
