How the formula works
Both kilojoule and centijoule measure the same physical quantity, so converting between them is a single multiplication. Multiply a value in kilojoules by 100000 to get centijoules. To reverse the conversion, multiply a centijoule value by 0.00001 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 Centijoule (cJ)?
A centijoule (cJ) is a metric-prefixed unit of energy equal to 10-2 joules, a fraction of a single joule, using the SI centi prefix.
How do I convert kilojoules to centijoules?
Multiply the kilojoule value by 100000 to get the equivalent in centijoules. For example, 5 kJ × 100000 = 500000 cJ.
Is this conversion exact?
Yes. Both units are defined against the SI base unit for this dimension, so the factor 100000 is an exact, non-rounded value.
Can I convert centijoules back to kilojoules?
Yes. Divide the centijoule value by 100000, or multiply it by 0.00001, to get kilojoules.
