Convert Thermochemical calorie per centimetre per second per degree Celsius to BTU per second per foot per degree Fahrenheit
Convert Thermochemical calorie per centimetre per second per degree Celsius (cal(th)/(cm·s·°C)) to BTU per second per foot per degree Fahrenheit (BTU/(s·ft·°F)) instantly and accurately.
Conversion Formula
BTU/(s·ft·°F) = cal(th)/(cm·s·°C) × 0.06715195834
About Thermochemical calorie per centimetre per second per degree Celsius
The cal(th)/(cm·s·°C) equals exactly 4.184/0.01 = 418.4 W/(m·K) (1 thermochemical calorie = 4.184 J). The CGS thermal conductivity unit dominant in US physics and chemistry before SI adoption. Copper: ≈0.921; aluminium: ≈0.489 cal(th)/(cm·s·°C). Not equal to cal(IT)/(cm·s·°C). 1 cal(th)/(cm·s·°C) = 418.4 W/(m·K).
About BTU per second per foot per degree Fahrenheit
The BTU per second per foot per degree Fahrenheit (BTU/(s·ft·°F)) equals (1055.05585262 × 9)/(0.3048 × 5) W/(m·K) ≈6230.6 W/(m·K). Equal to 3600 × BTU/(h·ft·°F). Reserved for extremely high-power transient applications in US engineering literature; copper ≈0.0617; carbon steel ≈0.0072 BTU/(s·ft·°F). 1 BTU/(s·ft·°F) = 3600 BTU/(h·ft·°F) ≈6230.6 W/(m·K).
