centijoule to millijoule
Convert centijoule (cJ) to millijoule (mJ). Use an editable energy converter, conversion formula, and reference table.
1 cJ = 10 mJ
Conversion formula
One centijoule equals 10 millijoule. Multiply your value in centijoule by this factor to get millijoule. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 centijoule:5 × 10 = 50 mJ

About these measurements
Energy can be transferred through work, heating, or electrical processes.
The base reference used here is the joule. One centijoule is 0.01 base units; one millijoule is 0.001 base units.
Important distinctions
Calorie and BTU definitions vary. These pages label thermochemical calories and International Table BTUs explicitly.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert cJ to mJ?
Multiply the quantity in cJ by 10. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the millijoule to centijoule converter.
