How to Convert Kilograms to Gallons
Since kilograms are a unit of mass and gallons are a unit of volume, which are different physical quantities, we need to know one more physical quantity of the ingredient or substance to convert between them. In this case, we need to account for the density of the substance whenever we do a conversion.
Therefore, to convert between kilograms and gallons of an ingredient or substance, we must either multiply or divide by its density, depending on which direction we are performing the conversion.
Kilograms to Gallons Formula
To convert a measurement in kilograms to gallons, divide the weight by the density of the ingredient or material. Note that in order for this to work, the density must be in kilograms per gallon (kg/gal).
If the density is given in grams per milliliter (g/mL), then first multiply the density by 3.7854 to convert to kg/gal.
For a density given in g/mL, you can use this simple formula to convert:
gallons = kilograms / 3.7854 × density
Thus, the volume in gallons is equal to the weight in kilograms divided by 3.7854 times the density (in g/mL) of the ingredient, substance, or material.
When to Convert Kilograms to Gallons
Kilograms 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. The density of dry ingredients can vary for a variety of reasons, such as compaction and clumping.
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.
Another useful application of weight and volume conversions is chemistry. When performing chemical reactions by combining separate chemicals to produce a new chemical, one must know the exact amount of each chemical to add in order to maximize the yield of the reaction.
It is common to mix powdered chemicals with liquid, or aqueous, chemicals, and this is where it becomes very useful to convert between weights and volumes.
A third application of weight and volume conversions is when shipping freight when calculating the volumetric weight for cargo and packages. Trucks, ships, and airplanes are limited in the amount of weight or volume they can transport, so if one of those quantities is known, but the limitation is on the other, then it becomes necessary to convert between the two so as not to overload the shipping vehicle.

What Is a Kilogram?
The formal definition of the kilogram changed in 2019. One kilogram was previously equal to the mass of the platinum-iridium bar, known as the International Prototype of the Kilogram, which was stored in Sèvres, France.
The kilogram, or kilogramme, is the SI base unit for mass and is also a multiple of the gram. In the metric system, "kilo" is the prefix for thousands, or 103. Kilograms can be abbreviated as kg; for example, 1 kilogram can be written as 1 kg.
A kilogram is frequently referred to as a unit of weight. While technically, a kilogram is a measure of mass, and weight is actually a measure of force, the two are equivalent as long as we are performing our calculations on Earth.
For example, an object with a mass of 1 kilogram weighs 1 kilogram on Earth, but only weighs one-sixth of that on the moon, yet still has the same mass.

What Is a Gallon?
The US liquid gallon is a unit of fluid volume equal to four quarts, eight pints, or sixteen cups. 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.
