How much does one gallon of water weigh?

• A. 8.00 lb
• B. 8.34 lb
• C. 10.00 lb
• D. 16.00 lb

Answer: (B)

One gallon of water weighs 8.34 pounds at room temperature, which is the standard unit conversion used in engineering and related fields. This weight can vary slightly with temperature and dissolved minerals, but 8.34 pounds is the accepted and standard weight for calculations involving water. This value is particularly important in various civil engineering applications, such as when calculating water loads for drainage systems, designing retaining walls, or assessing the weight of water in tanks. Knowing the weight of water is also crucial for determining material requirements and ensuring structures are engineered to handle specific loads. The other values do not accurately represent the weight of one gallon of water under standard conditions. Values like 8.00 lb, 10.00 lb, and 16.00 lb are either underestimations or overestimations and do not correspond to the typical weight of a gallon of water in practice.
