What is the weight of one cubic foot of water?

One cubic foot of water weighs approximately 62.5 pounds at standard temperature and pressure. This value is derived from the density of water, which is commonly accepted to be about 62.4 pounds per cubic foot at 4 degrees Celsius (the temperature at which water is most dense). The small difference between 62.4 and 62.5 is often rounded for practical purposes to 62.5 lbs.

Understanding the weight of water is crucial in various applications, including engineering, environmental science, and pest control where water management becomes vital. Knowing this weight helps practitioners calculate water-related solutions, such as the amount of herbicides to apply or the volume of water needed for specific treatments in aquatic pest control.
