Convert Thermochemical calorie per centimetre per second per degree Celsius to Milliwatt per metre degree Celsius
Convert Thermochemical calorie per centimetre per second per degree Celsius (cal(th)/(cm·s·°C)) to Milliwatt per metre degree Celsius (mW/(m·°C)) instantly and accurately.
Conversion Formula
mW/(m·°C) = cal(th)/(cm·s·°C) × 418400
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 Milliwatt per metre degree Celsius
The milliwatt per metre degree Celsius (mW/(m·°C)) equals exactly 1 mW/(m·K) = 10⁻³ W/(m·K) since temperature intervals 1 °C = 1 K. Used interchangeably with mW/(m·K) in building physics, insulation standards (EN ISO 10456), and material datasheets where Celsius is the preferred temperature scale. Still air ≈26 mW/(m·°C); mineral wool ≈35 mW/(m·°C). 1 mW/(m·°C) = 1 mW/(m·K) = 10⁻³ W/(m·K).
