How the formula works
Both kilojoule and decijoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in kilojoules by 10000 to get decijoules. To reverse the conversion, multiply a decijoule value by 0.0001 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 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 kilojoules to decijoules?
Multiply the kilojoule value by 10000 to get the equivalent in decijoules. For example, 5 kJ × 10000 = 50000 dJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 10000 is an exact, non-rounded value.
Can I convert decijoules back to kilojoules?
Yes. Divide the decijoule value by 10000, or multiply it by 0.0001, to get kilojoules.
