Convert Kilokelvin per watt to Degree Celsius per milliwatt

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

Kilokelvin per watt (kK/W)
Degree Celsius per milliwatt (°C/mW)

Conversion Formula

°C/mW = kK/W × 1

About Kilokelvin per watt

The kilokelvin per watt (kK/W) equals exactly 1000 K/W. Used for high thermal resistances in aerogel films, vacuum insulation panels with small contact area, and micron-scale thin-film insulation layers in microelectronics packaging. Numerically identical to °C/mW; both notations denote the same thermal resistance in different engineering contexts. 1 kK/W = 1000 K/W = 1 °C/mW.

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.
