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.
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.
