How the formula works
Both decajoule and decijoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in decajoules by 100 to get decijoules. To reverse the conversion, multiply a decijoule value by 0.01 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 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.
How do I convert decajoules to decijoules?
Multiply the decajoule value by 100 to get the equivalent in decijoules. For example, 5 daJ × 100 = 500 dJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 100 is an exact, non-rounded value.
Can I convert decijoules back to decajoules?
Yes. Divide the decijoule value by 100, or multiply it by 0.01, to get decajoules.
