Convert Thermochemical calorie per centimetre per second per degree Celsius to Watt per centimetre kelvin

Convert Thermochemical calorie per centimetre per second per degree Celsius (cal(th)/(cm·s·°C)) to Watt per centimetre kelvin (W/(cm·K)) instantly and accurately.

Thermochemical calorie per centimetre per second per degree Celsius (cal(th)/(cm·s·°C))
Watt per centimetre kelvin (W/(cm·K))

Conversion Formula

W/(cm·K) = cal(th)/(cm·s·°C) × 4.184

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 Watt per centimetre kelvin

The watt per centimetre kelvin (W/(cm·K)) equals exactly 100 W/(m·K). Used for highly conductive materials in electronics and cryogenics: silver ≈4.29, copper ≈3.85, aluminium ≈2.05 W/(cm·K); synthetic diamond ≈22 W/(cm·K). Common in semiconductor and power device literature where component dimensions are centimetre-scale. 1 W/(cm·K) = 100 W/(m·K).
