Thermal Conductivity converter
W/(m·K), BTU/(h·ft·°F) and the insulation k-value.
Thermal conductivity, the k-value, is how readily a material passes heat. Insulation data sheets in North America quote BTU·in/(h·ft²·°F), while European ones use W/(m·K). Lower numbers mean better insulation.
Result
1 W/(m·K) = 0.5777893165 BTU/(h·ft·°F)
Multiply the number of watts per meter kelvin by 0.577789316543.
Results are rounded for display. Double-check values for critical work.
