Convert Thermochemical calorie per centimetre per second per degree Celsius to International table calorie per centimetre per second per degree Celsius
Convert Thermochemical calorie per centimetre per second per degree Celsius (cal(th)/(cm·s·°C)) to International table calorie per centimetre per second per degree Celsius (cal(IT)/(cm·s·°C)) instantly and accurately.
Conversion Formula
cal(IT)/(cm·s·°C) = cal(th)/(cm·s·°C) × 0.9993312315
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 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).
