How much does 1 cubic foot of water weigh?

One cubic foot of water weighs approximately 62.55 pounds at a temperature of 39.2 degrees Fahrenheit, which is where water is most dense. This value is widely used in engineering and fluid calculations, making it a standard reference in various fields, including piping practices. The specific weight can vary slightly based on temperature and impurities in the water, but for most practical applications, the accepted weight is close to 62.55 pounds.

Using this value is crucial in high-pressure piping calculations, as the weight of the water impacts the pressure exerted on the piping system, the necessary strength of materials, and the overall design considerations for safe and effective operation. Understanding the weight of water is fundamental for professionals working with fluid systems, ensuring they can properly design and maintain those systems under various pressures and conditions.
