Thermal resistivity is a measure of a material's ability to resist the flow of heat. It quantifies how well a material can conduct heat and is the reciprocal of thermal conductivity.

Common units of measurement for thermal resistivity include square meter kelvin per watt (m²K/W) and square centimeter degree Celsius per watt (cm²°C/W).

• Used in the design of insulation materials
• Determines the effectiveness of materials in maintaining temperature
• Essential for understanding heat transfer in various industries
