What does 1 millijoule represent in terms of joules?

One millijoule is equal to 0.001 joules, representing a very small amount of energy typically used in scientific and engineering contexts.

How is the kilocalorie (IT) defined?

The kilocalorie (IT) equals 1,000 international-table calories, where an international-table calorie is 4.1868 joules.

When should I convert millijoules to kilocalories (IT)?

This conversion is useful when you need to express small energy amounts in heat-related units for thermodynamics, calorimetry, or engineering heat balance studies.
