How to Convert Pounds to Gallons

To convert a pound measurement to a gallon measurement, divide the weight by 8.345404 times the density of the ingredient or material.

You can use this simple formula to convert:

gallons = pounds / 8.345404 × ingredient density

Thus, the weight in gallons is equal to the pounds divided by 8.345404 times the density of the ingredient or material.

For example, here's how to convert 5 pounds to gallons for an ingredient with a density of 0.7 g/mL.
5 lb = 5 / 8.345404 × 0.7 = 0.855903052263 gal

Pounds and gallons are both commonly used to measure cooking ingredients.

For cooking applications, most chefs suggest measuring dry ingredients by weight rather than volume to improve accuracy in the measurements.[1] The density of dry ingredients can vary for a variety of reasons, such as compaction.

The best way to ensure an accurate conversion is to use a scale. When a scale is not available, a calculator like the one above is a good way to estimate the weight to volume conversion.

Pounds

Pounds are a widely used unit of mass/weight in the United States. The National Bureau of Standards approved the international definition of the pound for use in the United States in 1959 after an agreement between six nations referred to as the International Yard and Pound Agreement.[2]

One pound is equal to 16 ounces, or 0.45359237 kilograms. In the avoirdupois or apothecaries' systems, one pound is equal to 7,000 grains.[3]

The pound is a US customary and imperial unit of weight. A pound is sometimes also referred to as a common ounce. Pounds can be abbreviated as lb, and are also sometimes abbreviated as lbs, lbm, or #. For example, 1 pound can be written as 1 lb, 1 lbs, 1 lbm, or 1 #.

Gallons

The US liquid gallon is a unit of fluid volume equal to four quarts, eight pints, or sixteen cups.[4] The US liquid gallon should not be confused with the US dry gallon or the imperial gallon, which are different units of measure.

The gallon is a US customary unit of volume. Gallons can be abbreviated as gal; for example, 1 gallon can be written as 1 gal.
