Below are descriptions and historical context for each Thermal-Conductivity unit available in this converter.

Microwatt per meter-kelvin, used for very low conductivity materials like aerogels and vacuum insulation.

Milliwatt per meter-kelvin, common for insulation materials (foam: 20-40 mW/m·K).

Watt per meter-kelvin, SI unit for thermal conductivity. Water: 0.6, steel: 50, copper: 400 W/m·K.

Kilowatt per meter-kelvin, used for extremely high conductivity materials like diamond (2000 W/m·K).

Watt per centimeter-celsius, convenient for high-conductivity materials and thin films.

BTU per hour-foot-fahrenheit, traditional imperial unit used in US thermal engineering.

BTU-inch per hour-square foot-fahrenheit, used for insulation R-value calculations.

Calorie per second-centimeter-celsius, CGS unit still used in some scientific applications.

Kilocalorie per hour-meter-celsius, used in European building and HVAC standards.
