Convert Degree Celsius per watt to Kilokelvin per watt

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

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

Conversion Formula

kK/W = °C/W × 0.001

About Degree Celsius per watt

The degree Celsius per watt (°C/W) equals exactly 1 K/W since temperature intervals 1 °C = 1 K. It is the dominant notation in semiconductor, LED, and power electronics datasheets worldwide. Thermal resistance values such as RθJA (junction-to-ambient) and RθJC (junction-to-case) are almost universally quoted in °C/W. A package at 50 °C/W dissipating 2 W yields ΔT = 100 °C. 1 °C/W = 1 K/W.

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.
