Convert Kilokelvin per watt to Hour-degree Fahrenheit per BTU
Convert Kilokelvin per watt (kK/W) to Hour-degree Fahrenheit per BTU (h·°F/BTU) instantly and accurately.
Conversion Formula
h·°F/BTU = kK/W × 527.5279263
About Kilokelvin per watt
The kilokelvin per watt (kK/W) equals exactly 1000 K/W. Used for high thermal resistances in aerogel films, vacuum insulation panels with small contact area, and micron-scale thin-film insulation layers in microelectronics packaging. Numerically identical to °C/mW; both notations denote the same thermal resistance in different engineering contexts. 1 kK/W = 1000 K/W = 1 °C/mW.
About Hour-degree Fahrenheit per BTU
The h·°F/BTU equals (5/9 × 3600)/1055.05585262 K/W ≈ 1.8956 K/W. It is the traditional US unit for thermal resistance in HVAC, building science, and insulation engineering. A pipe fitting with R = 1 h·°F/BTU passes 1 BTU/h per °F driving difference. Appears in ASHRAE handbooks, ASTM C177, and older US plumbing codes. 1 h·°F/BTU ≈ 1.8956 K/W.
