How much does one gallon of water weigh?

One gallon of water weighs approximately 8.34 pounds under standard conditions (specifically at 62°F or 17°C). This value is widely accepted in scientific and practical contexts, as it provides a useful approximation for calculations involving water in various applications, including agriculture and pesticide application.

Understanding this weight is important when mixing solutions for pesticide applications to ensure accurate dosages and effective treatments. Water's weight can slightly vary based on temperature and impurities, but 8.34 pounds per gallon is a reliable standard for most practical purposes.
