What does calorie (IT) represent?

Calorie (IT) is a historical energy unit defined as the heat needed to raise 1 gram of water by 1°C under conditions for international steam tables, used previously in steam-engine and thermodynamics calculations.

What is Btu (IT) used for?

Btu (IT) quantifies heat energy, commonly in thermodynamic and engineering contexts such as heating, cooling equipment ratings, and combustion energy calculations using international steam table standards.

Why convert calorie (IT) to Btu (IT)?

Conversion aids in interpreting and integrating older thermodynamic data with modern British thermal unit-based energy standards for engineering and research applications.
