Kelvin per watt to kelvin per milliwatt
Type a value in K/W to get it in K/mW instantly.
0.002K/mW
That's 4× as insulating as a large finned heatsink, while a small clip-on heatsink is 2.5× higher. A 10 W part on it would sit about 20 °C above ambient.
What it means
How well does it get rid of heat?
Heatsink ratings assume free air. Forced airflow can halve the figure, and a poor thermal interface can add more resistance than the heatsink removes.
The math
How to convert K/W to K/mW
To convert kelvin per watt to kelvin per milliwatt, multiply by 0.001.
Example: 2 K/W × 0.001 = 0.002 K/mW.
In the other direction, 1 K/mW = 1,000 K/W.
