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 Kelvin per watt

The kelvin per watt (K/W) is the SI coherent unit for thermal resistance, defined as the temperature rise (K) per unit of steady-state power dissipation (W). Used universally in electronic component datasheets (junction-to-ambient, junction-to-case), heat sink ratings, and thermal circuit analysis. A CPU heatsink at 0.3 K/W raises temperature 30 K per 100 W. 1 K/W = 1 °C/W.
