Convert heat transfer coefficient units including watts per square meter-kelvin, watts per square meter-celsius, BTU per hour-square foot-Fahrenheit, calories per second-square centimeter-Celsius, and more.
W/(m²·K) to BTU/hr-ft²-°F:
1 W/(m²·K) = 0.17611 BTU/(hr·ft²·°F)
BTU/hr-ft²-°F to W/(m²·K):
1 BTU/(hr·ft²·°F) = 5.67826 W/(m²·K)
kW/(m²·K) to W/(m²·K):
1 kW/(m²·K) = 1,000 W/(m²·K)
cal/(s·cm²·°C) to W/(m²·K):
1 cal/(s·cm²·°C) = 41,840 W/(m²·K)
Heat transfer coefficient conversions are useful for heat exchangers, convection calculations, HVAC coils, condensers, evaporators, boilers, radiators, electronics cooling, and thermal system design.
Use this converter when comparing SI, U.S. customary, and CGS heat transfer coefficient units.
Your result shows the entered heat transfer coefficient converted from the starting unit into the selected ending unit. The calculator also shows the conversion rate used so you can verify the calculation.
For engineering and heat transfer work, make sure the coefficient unit matches your convection equation, equipment data sheet, heat exchanger model, or thermal design reference.
A heat transfer coefficient measures heat transfer rate per surface area per temperature difference.
The SI unit is watts per square meter-kelvin, abbreviated as W/(m²·K).
For temperature differences, W/(m²·K) and W/(m²·°C) are numerically equivalent.
One BTU per hour-square foot-Fahrenheit equals approximately 5.67826 W/(m²·K).
This converter is designed for heat transfer coefficient magnitude conversions, so it uses non-negative values.
