What does the kilojoule measure?

The kilojoule is an SI-derived unit of energy equal to 1,000 joules, representing work, heat, and other energy forms.

Why use the calorie (IT) unit?

Calorie (IT) is used for interpreting historical steam table data and classical thermodynamic calculations predating SI units.

Is the calorie (IT) unit still used today?

It is mostly historical and superseded by the joule, but still relevant when working with older engineering and thermodynamic records.
