This essential tool simplifies thermal engineering calculations for HVAC, building science, and material design professionals, ensuring precise unit conversions quickly and efficiently.
Formula:
The heat transfer coefficient (often denoted as h or U) quantifies the rate of heat transfer per unit area per unit temperature difference. Converting between different units involves specific conversion factors.
- 1 W/(m²·K) = 0.176110 BTU/(hr·ft²·°F)
- 1 BTU/(hr·ft²·°F) = 5.678263 W/(m²·K)
- 1 W/(m²·K) = 0.859845 kcal/(hr·m²·°C)
- 1 kcal/(hr·m²·°C) = 1.163 W/(m²·K)
- W/(m²·K): Watts per square meter Kelvin (SI unit for heat transfer coefficient)
- BTU/(hr·ft²·°F): British Thermal Units per hour square foot degree Fahrenheit
- kcal/(hr·m²·°C): Kilocalories per hour square meter degree Celsius
