Frequently Asked Questions
-
What does calorie (IT)/hour/square centimeter measure?
-
It measures the rate of heat transfer per unit area expressed with International Table calories delivered hourly across one square centimeter.
-
When should I use Btu (IT)/second/square foot units?
-
Btu (IT)/second/square foot units are suitable for reporting extreme radiative heat fluxes, such as in fire testing and high-temperature heating experiments.
-
Is this conversion exact for all applications?
-
While the conversion provides a reliable estimate, non-SI unit use and magnitude differences may introduce limitations needing careful interpretation.
