What does calorie (IT)/second represent?

Calorie (IT)/second is a power unit describing the rate at which heat energy in International Table calories is transferred each second.

Where is Btu (IT)/hour commonly used?

Btu (IT)/hour is commonly applied to rate HVAC equipment, boilers, and heating systems reflecting heat transfer per hour.

Why is converting between these units important?

It allows translation of historical or laboratory heat-transfer data into units widely used in industry for practical equipment rating and system design.
