How to Convert Milliliters to Ounces

Since milliliters are a unit of volume and ounces are a unit of mass, 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 milliliters and ounces of an ingredient or substance, we must either multiply or divide by its density, depending on which direction we are performing the conversion.

Milliliters to Ounces Formula

To convert a measurement in milliliters to ounces, multiply the volume by the density of the ingredient, substance, or material.Note that in order for this to work, the density must be in ounces per milliliter (oz/mL).

If the density is given in grams per milliliter (g/mL), then first divide the density by 28.3495 to convert to oz/mL.

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

ounces = milliliters × density / 28.3495

Thus, the weight in ounces is equal to the volume in milliliters times the density (in g/mL) of the ingredient or material divided by 28.3495.

This formula is for converting to ounces in weight, if you're trying to convert to a volume measurement in fluid ounces, try our milliliters to fluid ounces calculator.

When to Convert Milliliters to Ounces

Milliliters and ounces 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 volume to weight 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]
