The overall heat transfer coefficient (U-factor) of a double-pane window is $0.350 \text{ Btu}/(\text{h}\cdot\text{ft}^2\cdot^\circ\text{F})$. Convert this U-factor to its metric thermal resistance (RSI) equivalent. (Note: RSI is the reciprocal of the metric heat transfer coefficient in $\text{W}/(\text{m}^2\cdot\text{K})$, and $1 \text{ Btu}/(\text{h}\cdot\text{ft}^2\cdot^\circ\text{F}) \approx 5.67826 \text{ W}/(\text{m}^2\cdot\text{K})$)
