How much does 1 Imperial gallon weigh?

The weight of one Imperial gallon of water is approximately 10 pounds. This value is based on the density of water, which is generally considered to be around 8.34 pounds per US gallon at room temperature. However, in the case of the Imperial gallon, which is slightly larger than the US gallon (1 Imperial gallon is about 1.2 US gallons), the weight increases accordingly. Specifically, the Imperial gallon weighs approximately 10 pounds due to the difference in volume.

Understanding these measurements is crucial for various plumbing and engineering calculations, as accurate knowledge of liquid weights is needed for properly sizing pipes, determining tank capacities, and ensuring safe handling of fluids. This knowledge contributes to effective design and installation practices in plumbing systems.
