What is the main difference between Btu (IT)/pound/°F and Btu (th)/pound/°F?

Btu (IT)/pound/°F is based on the International Table British thermal unit, while Btu (th)/pound/°F uses the thermochemical British thermal unit. The difference affects the heat energy calculation but is very small.

When should I use this conversion?

Use this conversion when you need to align specific heat capacity values with thermochemical definitions for more precise HVAC, boiler, and heat exchanger calculations within Imperial unit contexts.

Can I ignore the conversion difference in all calculations?

For many practical engineering applications, the slight difference may be negligible; however, for high-precision thermal analyses, it is recommended to account for the conversion.
