How the formula works
Both microjoule and decajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in microjoules by 1.000000000e-07 to get decajoules. To reverse the conversion, multiply a decajoule value by 10000000 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 Decajoule (daJ)?
A decajoule (daJ) is a metric-prefixed unit of energy equal to 101 joules, using the SI deca prefix.
How do I convert microjoules to decajoules?
Multiply the microjoule value by 1.000000000e-07 to get the equivalent in decajoules. For example, 5 uJ × 1.000000000e-07 = 5.000000e-07 daJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 1.000000000e-07 is an exact, non-rounded value.
Can I convert decajoules back to microjoules?
Yes. Divide the decajoule value by 1.000000000e-07, or multiply it by 10000000, to get microjoules.
