What is a kilocalorie (IT)?

A kilocalorie (IT) is a unit of energy equal to 1,000 international-table calories, where each calorie is defined as 4.1868 joules, so 1 kcal (IT) equals 4,186.8 joules.

What does the therm measure?

The therm measures energy commonly used for natural gas quantities and equals 100,000 British thermal units, approximately 1.055×10^8 joules.

Why convert kilocalorie (IT) to therm?

Converting kilocalorie (IT) to therm helps translate energy data from heat and calorimetry contexts into units suitable for natural gas billing, engineering, and energy comparisons.
