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