Convert International table calorie per centimetre per second per degree Celsius to Milliwatt per metre kelvin

Convert International table calorie per centimetre per second per degree Celsius (cal(IT)/(cm·s·°C)) to Milliwatt per metre kelvin (mW/(m·K)) instantly and accurately.

International table calorie per centimetre per second per degree Celsius (cal(IT)/(cm·s·°C))
Milliwatt per metre kelvin (mW/(m·K))

Conversion Formula

mW/(m·K) = cal(IT)/(cm·s·°C) × 418680

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).

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).
