What is a millijoule?

The millijoule (mJ) is an SI derived unit of energy equal to one thousandth of a joule, used to measure small amounts of work or energy such as low-power laser pulses.

What is the calorie (IT)?

The calorie (IT), or International Steam Table calorie, is a historical unit of energy defined by the heat required to raise the temperature of 1 gram of water by 1 °C under international steam table conditions.

Why convert millijoules to calorie (IT)?

Conversion helps interpret or compare modern small-scale energy data with older thermodynamic measurements recorded in historical units used for steam-engine and heat calculations.
