A liquid with SG 0.92; given water density 62.4, its density in lb/ft^3?

Explanation:
Specific gravity compares density to that of water. With water’s density at 62.4 lb/ft^3, the liquid’s density is 0.92 × 62.4 = 57.408 lb/ft^3. Rounding to two decimals gives 57.41 lb/ft^3. So the density is 57.41 lb/ft^3. The result comes directly from SG being a ratio of densities, so you simply scale the water density by the SG.
