Convert Kelvin per horsepower to Millikelvin per watt
Convert Kelvin per horsepower (K/hp) to Millikelvin per watt (mK/W) instantly and accurately.
Conversion Formula
mK/W = K/hp × 1.34102209
About Kelvin per horsepower
The kelvin per horsepower (K/hp) equals 1/745.69987158 K/W ≈ 1.341 × 10⁻³ K/W. Used in mechanical engineering when rating engine cooling systems, gearbox oil coolers, and hydraulic heat exchangers alongside power expressed in horsepower. A transmission cooler at 0.05 K/hp raises fluid temperature 3.73 K per 75 hp of friction losses. 1 K/hp ≈ 1.341 × 10⁻³ K/W.
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.
