Heat Converters
Thermal Resistance Converter
Convert thermal resistance between kelvin per watt and imperial R-value units. R-value in °F·ft²·h/BTU divided by 5.678 gives RSI (m²·K/W) thermal resistance per area.

| Unit | Symbol | To kelvin/watt (K/W) | From kelvin/watt (K/W) |
|---|---|---|---|
| Kelvin/watt | K/W | 1 K/W = 1 K/W | 1 K/W = 1 K/W |
| Celsius/watt | °C/W | 1 °C/W = 1 K/W | 1 K/W = 1 °C/W |
| Fahrenheit·hour/BTU | °F·h/BTU | 1 °F·h/BTU = 1.89563424 K/W | 1 K/W = 0.52752793 °F·h/BTU |
| Fahrenheit·second/BTU | °F·s/BTU | 1 °F·s/BTU = 6,826.1352663 K/W | 1 K/W = 0.00014649578 °F·s/BTU |

Frequently asked questions
What units does this thermal resistance converter support?
It supports 4 units: Kelvin/watt (K/W), Celsius/watt (°C/W), Fahrenheit·hour/BTU (°F·h/BTU), Fahrenheit·second/BTU (°F·s/BTU).
What is the base unit of thermal resistance?
The SI reference unit is the kelvin/watt (K/W). Every conversion is computed by converting the input to the base unit, then from the base unit to the target unit, so chained precision is preserved.
Is this converter accurate?
Yes. Conversion factors use exact legal definitions where they exist (for example 1 in = 25.4 mm exactly) and CODATA/ISO constants otherwise. Results are shown to up to 10 significant figures.
