What is the weight of 1 gallon of water in pounds?

The weight of 1 gallon of water is commonly understood to be approximately 8.34 pounds at standard room temperature. This value is based on the density of water, which is close to 8.34 pounds per gallon at 62 degrees Fahrenheit, a temperature frequently used for measurement purposes.

Understanding this weight is crucial in wastewater management and other applications because it allows operators to calculate flow rates, determine the weight of water in systems, and make informed decisions about treatment processes based on the volume and weight of water being processed.

The other choices do not reflect the accepted weight of a gallon of water at standard temperature and pressure. Therefore, 8.34 pounds is the correct and widely recognized value for the weight of one gallon of water.
