What does Btu (IT) stand for?

Btu (IT) is a British thermal unit defined by the International Steam Tables, used to measure energy in thermodynamic calculations.

Why use kilocalorie (IT) instead of other calorie units?

Kilocalorie (IT) is based on the international-table calorie definition, commonly used in steam tables, thermodynamics, and some older literature.

Can I use this tool for other Btu or calorie definitions?

No, this tool specifically converts between Btu (IT) and kilocalorie (IT) and does not adjust for other unit definitions.
