STEP BY STEP
How to use thermal conductivity converter — w/m·k & btu
- Compare the output with the example below.
- Check the stated limitations before using the result.
IN PRACTICE
Example
1 W/(m·K) ≈ 6.93347 Btu_IT·in/(h·ft²·°F); 1 W/(cm·K) = 100 W/(m·K).
GOOD TO KNOW
Are W/(m·K) and W/(m·°C) equivalent?
Yes. Conductivity uses temperature differences, so a one-kelvin change equals a one-degree-Celsius change. Do not apply absolute temperature offsets.
Conductivity k is not a heat-transfer coefficient U or a thermal resistance R. Conversion preserves the material property at its stated temperature.
