What does kilocalorie (IT) represent?

Kilocalorie (IT) is a unit of energy equal to 1,000 international-table calories, where each calorie is defined as 4.1868 joules.

What is the Btu (th) unit used for?

Btu (th) is a thermochemical British thermal unit used to rate heating and cooling equipment and measure the energy content of fuels.

Why might there be discrepancies in conversions?

Minor differences arise because kilocalorie (IT) and Btu (th) rely on slightly different calorie definitions and assumptions about conditions.
