Convert thermal conductivity units including watts per meter-kelvin, watts per meter-celsius, BTU per hour-foot-Fahrenheit, calories per second-centimeter-Celsius, and more.
Watts per meter-kelvin to BTU/hr-ft-°F:
1 W/(m·K) = 0.577789 BTU/(hr·ft·°F)
BTU/hr-ft-°F to watts per meter-kelvin:
1 BTU/(hr·ft·°F) = 1.730735 W/(m·K)
Calories per second-centimeter-Celsius to W/(m·K):
1 cal/(s·cm·°C) = 418.4 W/(m·K)
Kilowatts per meter-kelvin to W/(m·K):
1 kW/(m·K) = 1,000 W/(m·K)
Thermal conductivity conversions are useful for insulation, wall assemblies, heat transfer calculations, materials engineering, HVAC, pipes, furnaces, heat exchangers, electronics cooling, and energy modeling.
Use this converter when comparing SI, U.S. customary, and CGS thermal conductivity units.
Your result shows the entered thermal conductivity converted from the starting unit into the selected ending unit. The calculator also shows the conversion rate used so you can verify the calculation.
For engineering, building, and heat transfer work, make sure the thermal conductivity unit matches your material data sheet, insulation reference, thermal model, or heat transfer formula.
Thermal conductivity measures how easily heat passes through a material.
The SI unit of thermal conductivity is watts per meter-kelvin, abbreviated as W/(m·K).
For temperature differences, W/(m·K) and W/(m·°C) are numerically equivalent.
No. Higher thermal conductivity means heat transfers more easily. Lower thermal conductivity is usually better for insulation.
This converter is designed for thermal conductivity magnitude conversions, so it uses non-negative values.
