Kilocalorie per centimetre per hour per degree Celsius (kcal/(cm·h·°C))
Thermochemical calorie per centimetre per second per degree Celsius (cal(th)/(cm·s·°C))

Conversion Formula

cal(th)/(cm·s·°C) = kcal/(cm·h·°C) × 0.2779636711

About Kilocalorie per centimetre per hour per degree Celsius

The kcal/(cm·h·°C) equals exactly 4186.8/36 W/(m·K) = 116.3 W/(m·K) (1 kcal(IT) = 4186.8 J; 1 h = 3600 s; 1 cm = 0.01 m). Used in older CGS-metric European and Soviet literature for metallic heat transfer. Steel: ≈0.137; copper: ≈3.31 kcal/(cm·h·°C). 1 kcal/(cm·h·°C) = 116.3 W/(m·K) = 100 × kcal/(m·h·°C).

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).
