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

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

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

Conversion Formula

W/(m·°C) = cal(th)/(cm·s·°C) × 418.4

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 metre degree Celsius

The watt per metre degree Celsius (W/(m·°C)) equals exactly 1 W/(m·K) since temperature intervals 1 °C = 1 K. Widely used in building physics (EN ISO 6946), HVAC engineering, and European material datasheets as an equivalent notation. Stone: ≈2.5 W/(m·°C); softwood timber: ≈0.14 W/(m·°C); glass wool: ≈0.04 W/(m·°C). 1 W/(m·°C) = 1 W/(m·K).
