Since kilograms are a unit of mass and milliliters 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 milliliters 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 Milliliters Formula

To convert a measurement in kilograms to milliliters, 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 milliliter (kg/mL).

If the density is given in grams per milliliter (g/mL), then first divide 1,000 by the density to convert to kg/mL.

For a density given in g/mL, you can use this simple formula to convert:

milliliters = kilograms × 1,000density

Thus, the volume in milliliters is equal to the weight in kilograms times 1,000 divided by the density of the ingredient, substance, or material.

For example, here's how to convert 5 kilograms to milliliters for an ingredient with a density of 0.7 g/mL.
milliliters = 5 kg × 1,0000.7 g/mL = 7,142.857 mL

When to Convert Kilograms to Milliliters

Kilograms and milliliters 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 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.[2]

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.

How Many Milliliters Are in a Kilogram?

The actual volume of a kilogram will vary depending on the density of the material. The table below shows how many milliliters of various wet and dry ingredients are in a kilogram.

What Is a Kilogram?

One kilogram is equal to 1,000 grams, 2.204623 pounds, or 1/1,000 of a metric ton.

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 2019 SI brochure now defines the kilogram using the Planck constant, and it is defined using the meter and second.[3] It is equal to the mass of 1,000 cubic centimeters, or milliliters, of water.

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 Milliliter?

The milliliter is a unit of volume equal to 1 cubic centimeter, 1/1,000 of a liter, or about 0.061 cubic inches.[4]

The milliliter is an SI unit of volume in the metric system. In the metric system, "milli" is the prefix for thousandths, or 10-3. A milliliter is sometimes also referred to as a millilitre. Milliliters can be abbreviated as mL, and are also sometimes abbreviated as ml or mℓ. For example, 1 milliliter can be written as 1 mL, 1 ml, or 1 mℓ.

Since one milliliter is equivalent to one cubic centimeter, milliliters are sometimes expressed using the abbreviation for a cubic centimeter (cc) for things such as medical dosages or engine displacements.
