What is a therm (US) unit?

The therm (US) is a non-SI unit of heat energy defined as 100,000 British thermal units, commonly used for measuring natural gas and heating energy in the United States.

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

Converting therm (US) to kilocalorie (th) allows energy measurements from natural gas or heating systems to be expressed in units commonly used for food energy content and thermal engineering.

Is the kilocalorie (th) used outside of nutrition?

Yes, the kilocalorie (thermochemical) is also used in certain thermal and chemical engineering contexts to represent heat quantities.
