Thermal conductivity conversion is widely used in construction, materials science, and HVAC design. In building insulation, the thermal conductivity of materials is calculated to evaluate energy consumption.
All values follow internationally accepted definitions and are rounded to the decimals you choose. The calculation runs entirely in your browser, so nothing is uploaded or stored on a server.
History & Background
The concept was proposed by French scientist Joseph Fourier in 1822 (Fourier's Law). He established that heat transfer is proportional to the temperature gradient and cross-sectional area.
Conversion Details
Thermal conductivity measures the ability of a material to conduct heat. The SI unit is W/(m·K).
Common conversions: 1 W/(m·K) ≈ 0.5778 BTU/(h·ft·°F).
