Convert Hour-degree Celsius per kilocalorie to Kelvin per horsepower

Convert Hour-degree Celsius per kilocalorie (h·°C/kcal) to Kelvin per horsepower (K/hp) instantly and accurately.

Hour-degree Celsius per kilocalorie (h·°C/kcal)
Kelvin per horsepower (K/hp)

Conversion Formula

K/hp = h·°C/kcal × 641.186476

About Hour-degree Celsius per kilocalorie

The h·°C/kcal equals 3600/4186.8 K/W ≈ 0.8598 K/W. Used in pre-SI European engineering literature (French, German, Italian) for heat transfer system calculations. A boiler with 1 h·°C/kcal resistance passes 1 kcal/h per °C temperature difference. Superseded by K/W and h·°C/W in modern standards. 1 h·°C/kcal ≈ 0.8598 K/W.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.
