Convert Hour-degree Celsius per kilocalorie to Kelvin per watt
Convert Hour-degree Celsius per kilocalorie (h·°C/kcal) to Kelvin per watt (K/W) instantly and accurately.
Conversion Formula
K/W = h·°C/kcal × 0.8598452279
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 Superseded by K/W and h·°C/W in modern standards. 1 h·°C/kcal ≈ 0.8598 K/W.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 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.
