Examples
-
2 calorie (IT)/second/square centimeter/°C equals 14756.63 Btu (th)/hour/square foot/°F.
-
0.5 calorie (IT)/second/square centimeter/°C equals 3689.16 Btu (th)/hour/square foot/°F.
Common Use Cases
-
Designing heat exchangers or cooling systems by specifying convective heat transfer coefficients in different unit systems.
-
Reporting experimental heat transfer measurements in laboratory studies involving convection or thermal resistance.
-
Performing thermal performance analysis of building components where imperial units are preferred.
-
Comparing energy and thermal envelope calculations between metric and imperial standards.
Tips & Best Practices
-
Ensure accurate measurement of temperature differences and surface areas to maintain conversion relevance.
-
Double-check unit selections before converting to avoid errors between °C and °F or cm² and ft² units.
-
Use this converter to facilitate communication and comparison of heat transfer data across regions using different units.
Limitations
-
Conversion involves differences in area and temperature units embedded within the factor which can affect interpretation.
-
Users should consider measurement accuracy and steady-state assumptions for valid results.
-
This tool converts units only—it does not calculate heat transfer coefficients from physical properties.
Frequently Asked Questions
-
What does calorie (IT)/second/square centimeter/°C measure?
-
It measures convective heat transfer coefficient as the rate of heat flow through a surface per second, per square centimeter, per degree Celsius temperature difference.
-
Why convert to Btu (th)/hour/square foot/°F?
-
Because Btu (th)/hour/square foot/°F is widely used in imperial-unit engineering and building analysis, especially in the US, facilitating design and comparison.
-
Can this tool convert other heat transfer units?
-
This tool specifically converts between calorie (IT)/second/square centimeter/°C and Btu (th)/hour/square foot/°F; other units are not supported.
