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 Minute-degree Fahrenheit per BTU

The minute-degree Fahrenheit per BTU (min·°F/BTU) equals (5/9 × 60)/1055.05585262 K/W ≈ 0.03159 K/W. Used in US refrigeration and air-conditioning engineering where capacity is expressed in BTU/min - 1 ton of refrigeration equals 200 BTU/min. Thermal resistance of evaporator and condenser circuits is conveniently quoted in this unit. 1 min·°F/BTU ≈ 0.03159 K/W = 60 s·°F/BTU.
