What does 1 Btu (IT)/hour represent?

It is a unit of power representing one International Table British thermal unit delivered or removed per hour, used mainly for heat transfer rates.

Why convert Btu (IT)/hour to calorie (th)/second?

This conversion is useful for interpreting heat transfer in terms of thermochemical calories per second, especially in older engineering literature and laboratory calorimetry.

Are there limitations to this conversion?

Yes, differences in unit definitions and rounding can affect accuracy, and extremely precise applications should use direct SI units like watts.

Limitations

Btu (IT)/hour assumes energy transfer uniformly over an hour and is specific to the International Table unit
Calorie (th)/second relies on the thermochemical calorie’s exact joule definition, which differs from other calorie definitions
Conversion precision may be affected by rounding and fixed unit definitions
Extreme precision requirements should consider direct SI unit measurements like watts
