What Is This Tool?
This converter allows you to translate heat flux density values from the unit calorie (th)/hour/square centimeter, which measures heat flow over small surfaces in older or lab settings, into Btu (IT)/second/square foot, a unit often used for intense thermal conditions such as fire testing and high-temperature experiments.

Common Use Cases
-
Interpreting heat flux data in legacy solar irradiance and thermal measurement literature.
-
Conducting laboratory calorimetry and small-area heat flux measurements for coatings or materials.
-
Evaluating radiative heat flux during fire testing and material fire-resistance assessments.
-
Specifying thermal loads in high-temperature experiments involving furnaces, lasers, or plasma.
-
Characterizing thermal exposure of materials and insulation in concentrated heat flux conditions.
Tips & Best Practices
-
Verify units carefully to prevent scale or timing errors during conversion.
-
Use this converter for translating older or metric-based heat flux data into fire testing units.
-
Consider the context of measurement conditions, as variations in test setup might affect results.
-
Confirm that the heat flux data is standardized before comparing converted values.
Limitations
-
Unit scale and timing differences require careful conversion to avoid mistakes.
-
The calorie (th)/hour/square centimeter is less prevalent in modern applications compared to SI or Btu units.
-
Variability in heat flux measurement conditions may limit direct comparability across methods.
Frequently Asked Questions
-
What does calorie (th)/hour/square centimeter measure?
-
It measures heat flux density as the amount of thermochemical calories transferred per hour over one square centimeter.
-
Where is Btu (IT)/second/square foot commonly used?
-
It is used to quantify high-intensity thermal power per area in fire testing, furnace experiments, and material thermal evaluations.
-
Why convert between these units?
-
Converting allows comparison and interpretation of heat flux data from older or small-scale metric units into widely used imperial units for high-temperature testing.
