How much does a Gallon of Water Weigh?

[Erwin]

I'm working on a science project and need to know the weight of a gallon of water. Can someone tell me how much it weighs in pounds or kilograms?

 

[Lucky]

A gallon of water in the U.S. weighs approximately 8.34 pounds (3.78 kilograms) at room temperature. The weight can vary slightly depending on temperature and impurities in the water. This measurement is crucial in scientific, cooking, and industrial contexts where accuracy is needed. For larger quantities, multiplying this weight provides quick estimates for transport or storage.

A gallon of water in the United States weighs about 8.34 pounds (3.78 kilograms) at room temperature. The weight can vary slightly depending on temperature since water expands or contracts with heat and cold.

A gallon of water weighs about 8.34 pounds (3.78 kilograms) at room temperature. This measurement applies to a US liquid gallon. In the UK, an imperial gallon of water weighs about 10 pounds (4.54 kilograms) due to its larger volume.

A US gallon of water will weigh approximately 8.34 pounds (3.78kg) while an imperial gallon will weigh approximately 10 pounds (4.54kg).

One gallon of water has a weight of approximately 8.34 pounds (3.78 kilograms) in room temperature. This measurement is pegged on a US liquid gallon. This weight may change slightly with temperature, as when colder water gets much denser, and when warmer it gets less dense.

At room temperature, one gallon of water weighs around 8.34 pounds (3.78 kilograms). The US liquid gallon serves as the basis for this measurement. This weight may vary slightly with temperature, as water becomes considerably denser in low temperatures and less dense in warmer ones.

A gallon of water weighs about 8.34 pounds (3.78 kilograms) at room temperature. This applies to a U.S. liquid gallon. An imperial gallon weighs more—around 10 pounds—because it holds a larger volume of water.

 

[Boogyman]

For most science projects, a gallon of water weighs about 8.34 pounds. That’s for a US liquid gallon at room temperature. If you’re doing calculations, this is the standard value people usually use.

And rated how weighty a gallon of water is? Single gallon of water 8.34 pounds (c. 3.78 kilograms), but it varies depending upon the temperature.

 

[Lucas]

A gallon of water weighs about 8.34 pounds (3.78 kilograms) at room temperature.
