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 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).
