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 Microjoule (uJ). Microjoule is 0.000001 joule units.
How do I convert Calorie to Microjoule?
Multiply the Calorie value by 4184000. For example, 10 cal × 4184000 = 4.184e+07 uJ.
Is the Calorie to Microjoule 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, Microjoule, such as in engineering, scientific, or industrial calculations.
Can I convert Microjoule back to Calorie?
Yes. Multiply the Microjoule value by 2.39006e-07 to get Calorie.

About this conversion
This page converts Calorie (cal) to Microjoule (uJ) within the engineering converter.
A thermochemical calorie is 4.184 joules. Microjoule is 0.000001 joule units.
The formula is uJ = cal × 4184000, 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.
