What is the kilocalorie (IT) unit defined as?

The kilocalorie (IT) equals 1,000 international-table calories, with one calorie defined as 4.1868 joules.

In what contexts is Btu (IT) commonly used?

Btu (IT) is frequently used in thermodynamic and engineering fields to express heating, cooling, and combustion energy.

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

Converting allows translation between calorie-based and British thermal unit systems used in engineering and older energy tables.
