## How to Convert Ounces to Milliliters

To convert an ounce measurement to a milliliter measurement, divide the weight multiplied by 28.349523 by the density of the ingredient or material.

You can use this simple formula to convert:

Thus, the weight in milliliters is equal to the ounces times 28.349523, divided by the density of the ingredient or material.

**For example,**here's how to convert 5 ounces to milliliters for an ingredient with a density of 0.7 g/mL.

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

Ounces 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.

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.

## Ounces

One ounce is a unit of mass/weight equal to 1/16 of a pound.
The common ounce should not be confused with the troy ounce, which is equal to 1/12 of a troy pound.^{[2]}

The ounce is a US customary and imperial unit of weight. Ounces can be abbreviated as *oz*; for example, 1 ounce can be written as 1 oz.

## Milliliters

The milliliter is a unit of volume equal to 1 cubic centimeter, 1/1,000 of a liter, or about 0.061 cubic inches.^{[3]}

The milliliter is an SI unit of volume in the metric system. In the metric system, "milli" is the prefix for 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.

Milliliters are sometimes expressed using the abbreviation cc for medical dosage, which is the abbreviation for the cubic centimeter.
