What Is This Tool?
This tool converts heat flux density measurements from calorie (IT)/hour/square centimeter, a non-SI unit measuring heat transfer rate over a small area, into Btu (th)/second/square inch, an imperial unit used for high heat flux conditions.
How to Use This Tool?
-
Enter the heat flux value in calories (IT)/hour/square centimeter.
-
Select calorie (IT)/hour/square centimeter as the input unit.
-
Choose Btu (th)/second/square inch as the output unit.
-
Click convert to get the equivalent heat flux density in Btu (th)/second/square inch.

Examples
-
10 calorie (IT)/hour/square centimeter converts to approximately 0.00007116 Btu (th)/second/square inch.
-
100 calorie (IT)/hour/square centimeter equals about 0.00071164 Btu (th)/second/square inch.
Common Use Cases
-
Reporting small-scale surface heat transfer rates in laboratory material testing using calorie-based units.
-
Converting heat flux measurements for fire-protection engineering and fire testing.
-
Characterizing intense localized heat from welding or plasma torch experiments using imperial units.
Tips & Best Practices
-
Be aware that calorie (IT)/hour/square centimeter is suited for low heat flux values, while Btu (th)/second/square inch applies to very high heat flux scenarios.
-
Use this conversion in contexts requiring precise compatibility between metric and imperial heat flux units.
-
Ensure calibration and standardization appropriate to your region or field to maintain measurement consistency.
Limitations
-
Calorie (IT)/hour/square centimeter is a non-SI unit reflecting relatively low heat fluxes compared to Btu (th)/second/square inch.
-
Conversions involve units with very different magnitudes, so care is needed to avoid precision loss.
-
Measurement standards and preferences vary, potentially requiring context-specific calibration.
Frequently Asked Questions
-
What does calorie (IT)/hour/square centimeter measure?
-
It measures heat flux density as the rate of heat energy transfer per hour through one square centimeter, using International Table calories.
-
In which industries is Btu (th)/second/square inch commonly used?
-
This unit is widely used in fire protection, welding, plasma torch experiments, and industrial furnace testing where very high localized heat fluxes are quantified.
-
Why convert from calorie (IT)/hour/square centimeter to Btu (th)/second/square inch?
-
Converting helps express heat flux values in imperial units compatible with certain engineering standards and high-temperature test protocols.
Key Terminology
