About the heat transfer coefficient converter
Convert heat transfer coefficient between W/(m²·K) (SI), kcal/(h·m²·°C), and BTU/(h·ft²·°F). The coefficient h relates surface heat flux to the temperature difference between a surface and a fluid — essential for HVAC, heat exchangers, and thermal-system design.
Frequently asked questions
-
How many W/(m²·K) is 1 BTU/(h·ft²·°F)?
One BTU/(h·ft²·°F) equals approximately 5.6783 W/(m²·K).
-
How is h different from U-value?
h is a surface coefficient between fluid and wall. U-value is the overall coefficient through an entire assembly, including all internal resistances.
-
Is high or low h better for cooling electronics?
High. A larger h removes more heat per degree of temperature rise.
