Convert US gallon

Before we look at the conversion, it is important to clarify the difference between the US gallon and the imperial (British) gallon:

• USgallon: equivalent to 3.78541 liters.
• Imperial gallon: equivalent to 4.54609 liters.

Conversion to liters

As the liter is the international standard unit of measurement for the volume of liquids, this is one of the most common conversions: 1 US gallon = 3.78541 liters.

Conversion to other volume units

1. Quarts (QT): 1 US gallon = 4 quarts
2. Pints (PT) : 1 US gallon = 8 pints
3. Cups : 1 US gallon = 16 cups
4. Fluid ounces (Fl Oz): 1 US gallon = 128 fluid ounces

Conversion to weight

The conversion from volume to weight depends on the density of the liquid. As an example, let's take water, which has a density of about 1 kg/L at room temperature:

1 US gallon of water weighs approximately 8.34 pounds (3.78541 liters x 1 kg/L = 3.78541 kg, converted to pounds).

Conclusion

It is important to note that these conversions may vary for other liquids, depending on their density. Before converting a liquid from volume to weight, make sure you have the correct density to hand
