Convert Degree Celsius per milliwatt to Microkelvin per watt
Convert Degree Celsius per milliwatt (°C/mW) to Microkelvin per watt (μK/W) instantly and accurately.
Conversion Formula
μK/W = °C/mW × 1000000000
About Degree Celsius per milliwatt
The degree Celsius per milliwatt (°C/mW) equals exactly 1000 K/W since 1 mW = 10⁻³ W and 1 °C = 1 K. Widely used in low-power semiconductor datasheets for characterising junction-to-ambient resistance: small-signal transistors, LEDs, photodiodes, and SMD resistors typically show RθJA of 50-500 °C/mW. A device at 200 °C/mW dissipating 5 mW rises 1 °C. 1 °C/mW = 1000 K/W = 1 kK/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.
