About the btu (it) inch per hour ft² °f
The btu (it) inch per hour ft² °f (BTU·in/(h·ft²·°F)) is a Imperial unit of thermal conductivity. The basis of US insulation R-values: R per inch = 1 ÷ this value.
About the watt per meter kelvin
The watt per meter kelvin (W/(m·K)) is a SI unit of thermal conductivity.
Where this conversion is used
Converting btu (it) inch per hour ft² °f to watts per meter kelvin comes up when insulation selection, heat-sink design, and building energy modelling. US insulation is sold by R-value, which is the reciprocal of conductivity per unit thickness — a higher R means a lower conductivity.
