What Is This Tool?
This tool converts heat flux density measurements from calorie (IT)/hour/square centimeter, a non-SI unit representing heat transfer rate per unit area, into foot pound/minute/square foot, an imperial unit measuring energy transfer rate per surface area. It facilitates translation between SI-based and legacy U.S. engineering units.

Limitations
-
Calorie (IT)/hour/square centimeter is a non-SI unit and less common in modern international standards
-
Foot pound/minute/square foot is mainly used in legacy U.S. engineering and HVAC contexts
-
Conversion precision depends on stable definitions of calories and time units
-
Using these units outside their typical contexts can complicate integration with SI-based systems
Frequently Asked Questions
-
Why is calorie (IT)/hour/square centimeter not commonly used today?
-
Because it is a non-SI unit, it is less favored in modern international standards that primarily rely on SI units like watts per square meter.
-
What types of applications use foot pound/minute/square foot?
-
This unit is used mainly in older U.S. engineering literature, HVAC reports, and thermal-flux measurements involving imperial units.
-
Can I convert values between these units manually?
-
Yes, by multiplying the calorie (IT)/hour/square centimeter value by the conversion factor 47.814488225, you obtain the equivalent foot pound/minute/square foot value.
Key Terminology
