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 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).
