Thermal Conductivity Units Converter

Coversion factor: 1 W/m·K = 0.01 W/cm·°C

Additional information

Thermal conductivity is a fundamental property of materials that describes their ability to conduct heat. It is the measure of how quickly heat can flow through a material when there is a temperature difference across it.

The standard unit for thermal conductivity in the International System of Units (SI) is watts per meter-kelvin (W/m·K).
