Frequently asked questions about thermal resistance
Are K/W and °C/W the same?+
Yes. A temperature difference of 1 K equals 1°C, so the numerical values are identical.
What is thermal resistance?+
Thermal resistance measures how much a material resists heat flow, analogous to electrical resistance.
Which units are supported?+
Kelvin per watt and Celsius per watt.
