Convert Degree Celsius per milliwatt to Millikelvin per watt

Convert Degree Celsius per milliwatt (°C/mW) to Millikelvin per watt (mK/W) instantly and accurately.

Degree Celsius per milliwatt (°C/mW)
Millikelvin per watt (mK/W)

Conversion Formula

mK/W = °C/mW × 1000000

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 Millikelvin per watt

The millikelvin per watt (mK/W) equals exactly 10⁻³ K/W. It is used for ultra-low thermal resistances in high-conductivity materials such as diamond heat spreaders (≈ 0.3 mK/W per mm thickness for 1 cm² area), liquid metal TIMs, and cryogenic heat links. Measuring at this scale requires precision power dissipation and calorimetric temperature sensing. 1 mK/W = 10⁻³ K/W.
