How to use this converter
Choose your starting and destination units, then enter a value. Results update as you type. You can swap the direction and choose the displayed precision.
Example: Kelvins per watt to Celsius degrees per watt
value × 1 = result
Here the starting unit is Kelvins per watt (K/W) and the result is in Celsius degrees per watt (°C/W). The calculator uses the catalog’s full factors before rounding the displayed result.
Worked examples
- 1 K/W ≈ 1 °C/W
- 10 K/W ≈ 10 °C/W
- 100 K/W ≈ 100 °C/W
Available thermal resistance options
Kelvins per watt (K/W) · Celsius degrees per watt (°C/W) · Fahrenheit hours per Btu (IT) (°F·h/Btu) · Fahrenheit seconds per Btu (IT) (°F·s/Btu)
Unit conventions
Thermal resistance (K/W) is distinct from area-normalized thermal insulance (m²·K/W).
