A material has a thermal conductivity of $1.5\text{ W}/(\text{m}\cdot\text{K})$. Convert this value to British Thermal Units per hour-foot-degree Fahrenheit ($\text{BTU}/(\text{h}\cdot\text{ft}\cdot{}^\circ\text{F})$). Use the conversion: $1\text{ W}/(\text{m}\cdot\text{K}) \approx 0.5778\text{ BTU}/(\text{h}\cdot\text{ft}\cdot{}^\circ\text{F})$.
