What is a therm unit used for?

A therm is a non-SI energy unit mainly used to measure natural gas quantities, commonly in utility billing and energy content specification.

How does Btu (IT) differ from other BTU definitions?

Btu (IT) is defined by the International Steam Tables with a precise energy value used in thermodynamics and engineering, which may differ slightly from other BTU definitions.

Why might conversion results vary slightly?

Differences in BTU definitions and reference conditions among countries and utilities can cause slight variations in the exact therm to Btu (IT) conversion.
