Thermal conductivity is a measure of a material's ability to conduct heat. It indicates how well a substance can transfer heat through conduction.

Common units of measurement for thermal conductivity include watts per meter-kelvin (W/mK), BTU per hour per foot per degree Fahrenheit (Btu/h ft °F), and calories per second per centimeter per degree Celsius (cal/s cm °C).

• Application and Importance:
• Essential for designing efficient heating and cooling systems
• Helps in selecting materials for insulation
• Important in industries such as manufacturing, construction, and electronics.
