About Millikelvin per watt

The millikelvin per watt (mK/W) equals exactly 10⁻³ K/W. It is used for ultra-low thermal resistances in high-conductivity materials such as diamond heat spreaders (≈ 0.3 mK/W per mm thickness for 1 cm² area), liquid metal TIMs, and cryogenic heat links. Measuring at this scale requires precision power dissipation and calorimetric temperature sensing. 1 mK/W = 10⁻³ K/W.

About Hour-degree Celsius per kilocalorie

The h·°C/kcal equals 3600/4186.8 K/W ≈ 0.8598 K/W. Used in pre-SI European engineering literature (French, German, Italian) for heat transfer system calculations. A boiler with 1 h·°C/kcal resistance passes 1 kcal/h per °C temperature difference. Superseded by K/W and h·°C/W in modern standards. 1 h·°C/kcal ≈ 0.8598 K/W.
