Convert Kelvin per watt to Kilokelvin per watt
Convert Kelvin per watt (K/W) to Kilokelvin per watt (kK/W) instantly and accurately.
Conversion Formula
kK/W = K/W × 0.001
About Kelvin per watt
The kelvin per watt (K/W) is the SI coherent unit for thermal resistance, defined as the temperature rise (K) per unit of steady-state power dissipation (W). Used universally in electronic component datasheets (junction-to-ambient, junction-to-case), heat sink ratings, and thermal circuit analysis. A CPU heatsink at 0.3 K/W raises temperature 30 K per 100 W. 1 K/W = 1 °C/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.
