Convert Kelvin per horsepower to Degree Celsius per watt
Convert Kelvin per horsepower (K/hp) to Degree Celsius per watt (°C/W) instantly and accurately.
Conversion Formula
°C/W = K/hp × 0.00134102209
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 Degree Celsius per watt
The degree Celsius per watt (°C/W) equals exactly 1 K/W since temperature intervals 1 °C = 1 K. It is the dominant notation in semiconductor, LED, and power electronics datasheets worldwide. Thermal resistance values such as RθJA (junction-to-ambient) and RθJC (junction-to-case) are almost universally quoted in °C/W. A package at 50 °C/W dissipating 2 W yields ΔT = 100 °C. 1 °C/W = 1 K/W.
