What is a kilocalorie (th)?

A kilocalorie (thermochemical), abbreviated as kcal (th), is a unit of energy defined as exactly 4,184 joules and commonly used to express the energy content in food and thermal engineering.

What is a therm (US)?

The US therm is a non-SI unit of heat energy equal to 100,000 British thermal units, used mainly in natural gas measurement and heating energy in the United States.

Why convert kilocalorie (th) to therm (US)?

Converting from kilocalorie (th) to therm (US) helps translate energy data between dietary, chemical, and US heating or natural gas billing contexts for practical application and comparison.
