Convert thermal conductivity units while treating kelvin and Celsius intervals consistently.
Primary converted value
1 W/(m·K) = 0.577789 Btu/(h·ft·°F)
Btu per hour foot Fahrenheit from Watt per meter kelvin.
1 W/(m·K) = 0.577789 Btu/(h·ft·°F)
Reverse conversion: 0.577789 Btu/(h·ft·°F) converts back to 1 W/(m·K).
k_{base}=k_{input}\times F_{from};\quad k_{output}=k_{base}/F_{to}
k_base = k_input x factor_from; k_output = k_base / factor_to.
1 W/(m·K) x 1 W/(m·K)/W/(m·K) = 1.000000 W/(m·K)
1.000000 W/(m·K) / 1.730735 W/(m·K)/Btu/(h·ft·°F) = 0.577789 Btu/(h·ft·°F)
Every row is converted from the same normalized base value, not from a rounded display result.

Thermal conductivity is a material property that relates conductive heat flux to temperature gradient through Fourier's law. W/(m K), W/(cm K), and imperial conductivity units can describe the same property, but the value itself may depend on temperature, direction, phase, composition, and test method.
Thermal Conductivity Converter applies this concept to its defined inputs and workflow. It normalizes to W/(m·K) and explains Fourier's law, diffusivity, conductance, and material limitations. Its governing relationship or workflow is stated as follows: k_base = k_input x factor_from; k_output = k_base / factor_to.
For this conversion, the user supplies Thermal conductivity value, From unit, To unit, and Number format; the tool returns primary conversion, base-unit normalization, conversion method, and reverse statement from the defined scale factors or equations. The selected units and sign or reference conventions must describe one consistent physical case. This converter does not model anisotropy, temperature dependence, or contact resistance.
Supported units include W/(m·K), W/(m·°C), mW/(m·K), kW/(m·K), Btu/(h·ft·°F), Btu·in/(h·ft^2·°F), and kcal/(h·m·°C).
Thermal conductivity normalizes to W/(m·K). W/(m·K) and W/(m·°C) have the same numerical scale because they use temperature differences.

| F_to | Target-unit factor or formula from base unit | base W/(m·K) |
| x_output | Converted output value | selected target unit |
