What is the weight of a cubic foot of water?

The weight of a cubic foot of water is 62.4 pounds, which is based on the standard definition used in various calculations, especially in plumbing and construction. This value represents the weight of fresh water at a specified temperature, typically around 39.2 degrees Fahrenheit (4 degrees Celsius), where water is densest.

This information is crucial for plumbing contractors, as understanding the weight of water helps in assessing load-bearing requirements for pipes, tanks, and other plumbing fixtures. Additionally, it plays an important role in calculating water pressure and determining the appropriate size and materials for plumbing systems. This knowledge can directly impact the design and safety of plumbing installations.
