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 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.
