What Is This Tool?
This converter transforms heat transfer coefficient values from Btu (th)/hour/square foot/°F, an imperial unit, to calorie (IT)/second/square centimeter/°C, a metric unit. It helps translate thermal transmittance and convective heat transfer data between different measurement systems for compatibility in engineering and research.

Tips & Best Practices
-
Ensure steady-state and uniform temperature conditions when applying conversions
-
Verify unit consistency, especially temperature scales and area measurements
-
Use the tool for heat transfer coefficients only, avoiding unrelated thermal properties
-
Cross-check converted results with domain standards for accuracy
-
Apply conversions carefully when comparing international datasets or literature
Limitations
-
Conversion presumes steady-state conditions and uniform temperature differences
-
Differences between °F and °C scales, and square foot vs. square centimeter areas require precise handling
-
Conversion strictly applies to heat transfer coefficients, not other thermal properties
Frequently Asked Questions
-
What does 1 Btu (th)/hour/square foot/°F represent?
-
It represents the rate of heat transfer through one square foot of area for a one-degree Fahrenheit temperature difference, quantifying convective or conductive heat flow per unit area per temperature difference.
-
Why convert Btu (th)/hour/square foot/°F to calorie (IT)/second/square centimeter/°C?
-
Converting between these units allows compatibility in design, analysis, and reporting across imperial and metric measurement systems, particularly when working with international standards or different literature.
-
Can this conversion be used for all thermal properties?
-
No, this unit conversion is specific to heat transfer coefficients and should not be applied to unrelated thermal properties.
