How the watt per meter per kelvin to btu per hour per foot per °f conversion works
Multiply by 0.5777893165 to go from watt per meter per kelvin to btu per hour per foot per °f:
BTU/(h·ft·°F) = W/(m·K) × 0.5777893165
Going the other way, multiply by 1.730734666, which is the same as dividing by 0.5777893165.
