How the formula works
Both decijoule and decajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in decijoules by 0.01 to get decajoules. To reverse the conversion, multiply a decajoule value by 100 to get back to decijoules.
Frequently asked questions
What is Decijoule (dJ)?
A decijoule (dJ) is a metric-prefixed unit of energy equal to 10-1 joules, a fraction of a single joule, using the SI deci 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 decijoules to decajoules?
Multiply the decijoule value by 0.01 to get the equivalent in decajoules. For example, 5 dJ × 0.01 = 0.050000 daJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 0.01 is an exact, non-rounded value.
Can I convert decajoules back to decijoules?
Yes. Divide the decajoule value by 0.01, or multiply it by 100, to get decijoules.
