Convert International table calorie per centimetre per second per degree Celsius to Thermochemical calorie per centimetre per second per degree Celsius
Convert International table calorie per centimetre per second per degree Celsius (cal(IT)/(cm·s·°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) = cal(IT)/(cm·s·°C) × 1.000669216
About International table calorie per centimetre per second per degree Celsius
The cal(IT)/(cm·s·°C) equals exactly 4.1868/0.01 = 418.68 W/(m·K) (1 international table calorie = 4.1868 J). Used in pre-SI thermodynamics, steam tables, and international heat transfer references. Copper: ≈0.920 cal(IT)/(cm·s·°C). Slightly larger than cal(th)/(cm·s·°C). 1 cal(IT)/(cm·s·°C) = 418.68 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).
