Convert Kilocalorie per metre per hour per degree Celsius to Thermochemical calorie per centimetre per second per degree Celsius
Convert Kilocalorie per metre per hour per degree Celsius (kcal/(m·h·°C)) to Thermochemical calorie per centimetre per second per degree Celsius (cal(th)/(cm·s·°C)) instantly and accurately.
Conversion Formula
cal(th)/(cm·s·°C) = kcal/(m·h·°C) × 0.002779636711
About Kilocalorie per metre per hour per degree Celsius
The kcal/(m·h·°C) equals exactly 4186.8/3600 W/(m·K) = 1.163 W/(m·K) (1 kcal(IT) = 4186.8 J). Used in pre-SI continental European engineering literature, older DIN/BS standards, and Soviet-era technical documentation. Brick: ≈0.6; dense concrete: ≈1.3; carbon steel: ≈38 kcal/(m·h·°C). 1 kcal/(m·h·°C) = 1.163 W/(m·K).
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).
