What is a calorie (IT)/second?

A calorie (IT)/second quantifies the rate of energy transfer of one International Table calorie per second, used to express thermal power or heat-transfer rates.

When should I convert from calorie (IT)/second to Btu (th)/hour?

This conversion is useful when translating heat-transfer data from historical or lab contexts to practical units widely used in HVAC and building energy management.

Can I use this converter for all types of heat transfer?

It is most suitable for steady heat transfer rates. Variable or transient heat transfer requires more detailed evaluation beyond this simple conversion.
