How to convert thermal resistance

All 5 thermal resistance units are converted through a single base unit, so any unit can be converted to any other. Enter a value, choose the units and press Convert, or open a conversion page for the exact factor and a reference table.

For example, 1 kelvin per watt (K/W) = 0.527528 degree fahrenheit hour per btu it (°F·h/Btu (IT)).

Thermal Resistance unit definitions

Kelvin per Watt (K/W)
Kelvin per watt is the SI unit of thermal resistance: the temperature rise across a component per watt of heat flowing through it. Heat sinks are rated in K/W, which is the same as °C/W.
