The watt per meter-Kelvin is the SI derived unit of thermal conductivity, expressing how well a material conducts heat.
It follows directly from Fourier's law of heat conduction and became standard for comparing insulation quality in material science.
Measurement system: International System of Units (SI). SI equivalent: Base SI thermal conductivity unit.
