How to Convert Grams to Gallons

Scales are used to measure weight

To convert a gram measurement to a gallon measurement, divide the weight by 3,785.41178 times the density of the ingredient or material.

You can use this simple formula to convert:

gallons = grams3,785.41178 × ingredient density

Thus, the weight in gallons is equal to the grams divided by 3,785.41178 times the density of the ingredient or material.

For example, here's how to convert 5,000 grams to gallons for an ingredient with a density of 0.7 g/mL.
5,000 g = 5,0003,785.41178 × 0.7 = 1.886943 gal

Grams 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.

Grams

A gram is the mass/weight equal to 1/1,000 of a kilogram and is roughly equivalent to the mass of one cubic centimeter of water.

The gram, or gramme, is an SI unit of weight in the metric system. Grams can be abbreviated as g; for example, 1 gram can be written as 1 g.

Gallons

The US liquid gallon is a unit of fluid volume equal to four quarts, eight pints, or sixteen cups.[2] 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.
