1 W/(m²·K) = 0.1761101837 BTU (IT)/(h·ft²·°F)
1 BTU (IT)/(h·ft²·°F) = 5.678263341 W/(m²·K)
To convert watt per square meter kelvin to btu (it) per hour square foot fahrenheit, multiply by 0.1761101837.
To convert btu (it) per hour square foot fahrenheit to watt per square meter kelvin, multiply by 5.678263341.
Example: convert 10 W/(m²·K) to BTU (IT)/(h·ft²·°F)
10 × 0.1761101837 = 1.7611018369 BTU (IT)/(h·ft²·°F)
Short background on the units used in this conversion.
The watt per square meter kelvin (W/(m²·K)) is the SI unit of heat transfer coefficient — convective heat flux per unit area per unit temperature difference.
Watts per square meter kelvin rate convection at walls, heat exchangers, and finned surfaces in HVAC and process engineering.
BTU (IT) per hour square foot Fahrenheit is an imperial heat transfer coefficient equal to about 5.678 W/(m²·K).
This BTU-based convection unit appears in US building codes, coil ratings, and legacy HVAC engineering tables.
BTU (IT)/(h·ft²·°F) = W/(m²·K) × 0.1761101837W/(m²·K) = BTU (IT)/(h·ft²·°F) × 5.678263341, using the same exact factors as this converter.Jump to any heat transfer coefficient conversion starting from watt per square meter kelvin — including the reverse direction and every other unit in our dataset.
