Older units like calorie (th)/hour/cm² are primarily used in historical or legacy contexts
-
Conversions require careful attention to unit definitions and should not be assumed interchangeable without verification
Frequently Asked Questions
-
What does calorie (th)/hour/square centimeter measure?
-
It measures the rate of heat flow per unit area, specifically the heat transferred in thermochemical calories each hour across one square centimeter.
-
Why convert to kilocalorie (IT)/hour/square meter?
-
Converting to kilocalorie (IT)/hour/square meter helps standardize heat flux data for larger surface areas and aligns with modern energy audit and building physics standards.
-
Are these units commonly used in modern measurements?
-
Calorie (th)/hour/cm² is mostly found in historical and some specialized engineering literature, while kilocalorie (IT)/hour/m² is more commonly used in building physics and HVAC applications.
