Conversion Formula

mW/(m·K) = 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 kelvin

The milliwatt per metre kelvin (mW/(m·K)) equals exactly 10⁻³ W/(m·K). Used for gases and ultra-low thermal conductivity solids: still air ≈26 mW/(m·K), CO₂ ≈16 mW/(m·K), aerogels 12-20 mW/(m·K), vacuum insulation panels ≈5 mW/(m·K). Standard insulation products are typically specified in mW/(m·K). 1 mW/(m·K) = 10⁻³ W/(m·K) = 0.1 mW/(cm·K).
