About Microwatt per metre kelvin
The microwatt per metre kelvin (µW/(m·K)) equals exactly 10⁻⁶ W/(m·K). Used for near-vacuum conditions and evacuated superinsulation systems where the effective thermal conductivity falls well below the mW/(m·K) range. Evacuated multi-layer insulation (MLI) at high vacuum can reach 0.001-10 µW/(m·K) effective conductivity. Completes the SI prefix chain below mW/(m·K). 1 µW/(m·K) = 10⁻⁶ W/(m·K) = 10⁻³ mW/(m·K).
About Kilocalorie per centimetre per hour per degree Celsius
The kcal/(cm·h·°C) equals exactly 4186.8/36 W/(m·K) = 116.3 W/(m·K) (1 kcal(IT) = 4186.8 J; 1 h = 3600 s; 1 cm = 0.01 m). Used in older CGS-metric European and Soviet literature for metallic heat transfer. Steel: ≈0.137; copper: ≈3.31 kcal/(cm·h·°C). 1 kcal/(cm·h·°C) = 116.3 W/(m·K) = 100 × kcal/(m·h·°C).
