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.

A slab shows hot and cold sides, heat flow, and q equals k A delta T over thickness.
Convert thermal conductivity values used in heat conduction, materials, insulation, and simulation setup.
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.

| x_input | Entered value | selected source unit |
| F_from | Source-unit factor or formula to base unit | base W/(m·K) |
| x_base | Normalized base-unit value | W/(m·K) |
| F_to | Target-unit factor or formula from base unit | base W/(m·K) |
| x_output | Converted output value | selected target unit |
