Hour-degree Celsius per kilocalorie (h·°C/kcal)
Microkelvin per watt (μK/W)

Conversion Formula

μK/W = h·°C/kcal × 859845.2279

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 Superseded by K/W and h·°C/W in modern standards. 1 h·°C/kcal ≈ 0.8598 K/W.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 Microkelvin per watt

The microkelvin per watt (μK/W) equals exactly 10⁻⁶ K/W. Used in ultra-precision cryogenic and nanotechnology research to characterise thermal contact resistance of atomically bonded interfaces, van der Waals heterostructures, and superconducting qubit heat links at millikelvin temperatures. Also quoted for on-chip thermal connections in quantum processor prototypes. 1 μK/W = 10⁻⁶ K/W.
