What does Btu (IT) stand for?

Btu (IT) refers to the British thermal unit defined by the International Steam Tables, used to measure energy in thermodynamic and engineering settings.

Why convert Btu (IT) to kilocalorie (th)?

Converting these units helps translate heat energy data between engineering contexts and fields like nutrition and thermal chemistry where kilocalorie (th) is more common.

Is the kilocalorie (th) the same as the calorie used in food labeling?

Kilocalorie (th) is defined thermochemically and is widely used in energy calculations, but older nutritional calories might differ in definition.
