To convert the density of mercury from g/cm^3 to lb/in^3, we use the conversion factors: 1 inch = 2.54 cm and 1 lb = 453.592 g. Therefore, $13.6 \, \text{g/cm}^3 = 13.6 \times \frac{1}{453.592} \, \text{lb/g} \times \left(\frac{2.54}{1}\right)^3 \, \text{cm}^3/\text{in}^3 \approx 0.491 \, \text{lb/in}^3$.
