How many pounds of milk are there in one gallon, to the hundredth?

The correct amount of milk in one gallon is approximately 8.62 pounds. This value is the result of the liquid density of cow's milk, which averages around 8.6 to 8.7 pounds per gallon, depending on its composition and temperature.

In the context of dairy evaluation, understanding the weight of milk is essential for various calculations, including feed efficiency, pricing, and yield determination. The standard measure for cow's milk density allows for consistent unit conversion across different applications in dairy science. Thus, using 8.62 pounds aligns with precise scientific practices in evaluating dairy output.

This value is slightly more than the density of water, which is about 8.34 pounds per gallon, reflecting the additional solutes present in milk such as fats, proteins, and minerals.
