## How to Convert Thermal Conductivity Units
### Formula
**BTU/(hr·ft·°F) = W/(m·K) x 0.5778**
Thermal conductivity describes how well a material conducts heat. The SI unit is Watts per meter-Kelvin. The imperial unit is BTU per hour-foot-degree Fahrenheit. The conversion factor of 0.5778 combines the energy conversion (W to BTU/hr), length conversion (m to ft), and temperature conversion (K to °F interval).
### Reference Values
| Material | W/(m·K) |
|---|---|
| Copper | 401 |
| Aluminum | 237 |
| Glass | 1.0 |
| Wood | 0.12-0.17 |

计算示例
Convert 1 W/(m·K) to BTU/(hr·ft·°F).
- Apply the conversion factor: 1 W/(m·K) = 0.5778 BTU/(hr·ft·°F)
- BTU/(hr·ft·°F) = 1 * 0.5778 = 0.5778
- Also: 1 W/(m·K) = 0.002388 cal/(s·cm·°C)
