Frequently asked questions
What is the source unit in this conversion?
The source unit is the Calorie (cal). A thermochemical calorie is 4.184 joules.
What is the destination unit in this conversion?
The destination unit is the Millijoule (mJ). Millijoule is 0.001 joule units.
How do I convert Calorie to Millijoule?
Multiply the Calorie value by 4184. For example, 10 cal × 4184 = 41840 mJ.
Is the Calorie to Millijoule conversion exact?
Yes. Both units belong to the same engineering measurement family (energy), so the ratio between them is a fixed, defined value rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in Calorie needs to be compared with, or reported in, Millijoule, such as in engineering, scientific, or industrial calculations.
Can I convert Millijoule back to Calorie?
Yes. Multiply the Millijoule value by 0.000239006 to get Calorie.

About this conversion
This page converts Calorie (cal) to Millijoule (mJ) within the engineering converter.
A thermochemical calorie is 4.184 joules. Millijoule is 0.001 joule units.
The formula is mJ = cal × 4184, based on each unit's fixed relationship to the energy base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
