What is the weight of one gallon of water?

The weight of one gallon of water is approximately 8.345 pounds. This figure is based on the fact that the density of water is about 62.4 pounds per cubic foot, and since there are 7.48 gallons in a cubic foot, you can derive the weight of a gallon of water from this density conversion.

This standard measurement takes into account that the weight can vary slightly depending on temperature and impurities in the water, but for practical purposes, the accepted weight for a gallon of water is indeed approximately 8.345 pounds. This value is often used in various fields, including engineering, environmental science, and cooking, ensuring consistency in calculations and measurements.
