What is the weight of one cubic foot of water?

The weight of one cubic foot of water is 62.4 lbs at a temperature of 4 degrees Celsius (39.2 degrees Fahrenheit) where water reaches its maximum density. This value is crucial in various engineering and environmental calculations, especially in water resource management and hydrology. Understanding the weight of water is vital for designing structures like dams, reservoirs, and pipelines that hold or convey water.

This figure of 62.4 lbs per cubic foot consistently serves as a standard reference in civil engineering and fluid mechanics, making it essential knowledge for professionals working with surface water. Other options present weights that do not reflect the standard weight of water, highlighting the importance of precision in calculations involving water volume.
