How much does one gallon of water weigh approximately?

One gallon of water weighs approximately 8.33 pounds at standard temperature and pressure. This value is useful to know for a variety of applications, especially in landscaping and horticulture, where water weight plays an important role in irrigation planning, soil saturation calculations, and overall landscape maintenance.

Understanding the weight of water is critical for landscape contractors when determining how much water can be transported or stored, as well as for assessing the load that soil can handle. This knowledge can also help in calculating the necessary equipment and logistics when planning for irrigation systems or water features in a landscape design.

The other options present weights that are not consistent with the commonly accepted figure for a gallon of water, making them inaccurate for practical applications in landscaping and other related fields.
