Short background on the units used in this conversion.
Kelvin per watt (K/W) is the SI unit of thermal resistance — the temperature difference per unit heat flow rate through a layer or assembly.
Kelvin per watt quantifies insulation layers, junctions, and composite walls when building R-value stacks in SI units.
Degree Fahrenheit hour per BTU (IT) is an imperial thermal resistance unit equal to about 1.896 K/W.
°F·h/BTU (IT) appears in US insulation R-value derivations and legacy building-envelope thermal tables.
°F·h/BTU (IT) = K/W × 0.5275279006K/W = °F·h/BTU (IT) × 1.895634333, using the same exact factors as this converter.Jump to any thermal resistance conversion starting from kelvin per watt — including the reverse direction and every other unit in our dataset.
