Thermal Conductivity Converter
Convert thermal conductivity between W/(m·K) and BTU/(h·ft·°F) using the SI value as reference.
How to use
- Enter material thermal conductivity and choose the datasheet/target unit between W/(m·K) and BTU/(h·ft·°F).
Capabilities and scope
Compare two engineering units for the material property governing heat flow under a temperature gradient.
How it works
The implementation uses 1 BTU/(h·ft·°F)≈1.730735 W/(m·K).
Example
0.5 W/(m·K) is about 0.288895 BTU/(h·ft·°F).
Useful for
- Compare insulation conductivity in SI/customary units
- Align material datasheet units
- Convert inputs for thermal analysis
Before you use it
- It only converts conductivity; thickness-dependent thermal resistance (R-value) and overall U-value are not calculated.
- Material conductivity can vary with temperature.

Frequently asked questions
Does it convert R-values too?
No. R-value combines material conductivity with thickness and requires a separate calculation.
