What is a pound-force inch?

A pound-force inch is a unit of energy representing work done by a force of one pound acting through a displacement of one inch, typically used in US mechanical engineering contexts.

What does a therm (US) represent?

The therm (US) is a unit of heat energy equal to 100,000 British thermal units, commonly used in the US for natural gas measurement and heating energy calculations.

Why is the conversion factor between lbf·in and therm (US) so small?

Because pound-force inch represents very small mechanical energy whereas therm (US) measures large heat energy quantities, leading to a very small numerical conversion factor.
