How the formula works
Both kilojoule and decajoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in kilojoules by 100 to get decajoules. To reverse the conversion, multiply a decajoule value by 0.01 to get back to kilojoules.
Frequently asked questions
What is Kilojoule (kJ)?
A kilojoule (kJ) equals 1,000 joules and is commonly used on nutrition labels outside the United States.
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 kilojoules to decajoules?
Multiply the kilojoule value by 100 to get the equivalent in decajoules. For example, 5 kJ × 100 = 500 daJ.
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 decajoules back to kilojoules?
Yes. Divide the decajoule value by 100, or multiply it by 0.01, to get kilojoules.
