How to Convert Milliliters to Fluid Ounces

To convert a measurement in milliliters to a measurement in fluid ounces, multiply the volume by the following conversion ratio: 0.033814 fluid ounces/milliliter.

Since one milliliter is equal to 0.033814 fluid ounces, you can use this simple formula to convert:

fluid ounces = milliliters × 0.033814

The volume in fluid ounces is equal to the volume in milliliters multiplied by 0.033814.

For example, here's how to convert 5 milliliters to fluid ounces using the formula above.

fluid ounces = (5 mL × 0.033814) = 0.16907 fl oz

Milliliters and fluid ounces are both units used to measure volume. Keep reading to learn more about each unit of measure.

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.[1]

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.

What Is a Fluid Ounce?

The US fluid ounce is a unit of volume equal to 1/16 of a pint or 1/8 of a cup. The fluid ounce is sometimes referred to as just an "ounce" but should not be confused with the unit of weight. One fluid ounce is equal to approximately 29.5735 milliliters, but in nutrition labeling, one fluid ounce is rounded to exactly 30 milliliters.[2]

The fluid ounce is a US customary unit of volume. Fluid ounces can be abbreviated as fl oz, and are also sometimes abbreviated as oz fl. For example, 1 fluid ounce can be written as 1 fl oz or 1 oz fl.
