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).
About Kilocalorie per metre per hour per degree Celsius
The kcal/(m·h·°C) equals exactly 4186.8/3600 W/(m·K) = 1.163 W/(m·K) (1 kcal(IT) = 4186.8 J). Used in pre-SI continental European engineering literature, older DIN/BS standards, and Soviet-era technical documentation. Brick: ≈0.6; dense concrete: ≈1.3; carbon steel: ≈38 kcal/(m·h·°C). 1 kcal/(m·h·°C) = 1.163 W/(m·K).
