About these units
The watt per square meter kelvin (W/(m²·K)) is an SI base or derived unit of heat transfer coefficient.
The btu per hour square foot °f (BTU/(h·ft²·°F)) is an imperial unit of heat transfer coefficient, equal to 5.6782633 watts per square meter kelvin.
Going the other way, 1 btu per hour square foot °f = 5.6782633 watts per square meter kelvin. The U-value of a window, wall or heat exchanger is the heat flow per unit area per degree of temperature difference. Building codes in Europe quote W/(m²·K), while US codes use BTU/(h·ft²·°F). One US unit is about 5.678 metric units.
