Milliliters to Fluid Ounces Converter
Milliliters to Fluid Ounces Converter
Milliliters to fluid ounces is constantly needed for reading bottle and container labels, recipe conversions, and medication dosing when comparing metric (mL) product labeling to the US customary fluid ounce.
This tool goes beyond mL and US fl oz: the "From" and "To" dropdowns cover the full range of volume units — metric, US customary, Imperial (including the distinct Imperial fluid ounce), and specialized units.
- Conversion factor: 1 milliliter = 0.033814 U.S. fluid ounces (and 1 U.S. fluid ounce = exactly 29.5735295625 mL).
- Fully flexible: change either dropdown to convert between any two of the 40+ supported volume units.
- Two different fluid ounces: the U.S. fluid ounce (29.5735 mL) and the Imperial fluid ounce (28.4131 mL) are close but not identical — select "Ounce (Imperial fluid)" if your source is UK-based.
How many fluid ounces are in a milliliter?
1 milliliter equals approximately 0.0338 U.S. fluid ounces. To convert, divide the milliliter value by 29.5735295625, or multiply by 0.033814.
Why do US and UK fluid ounces differ?
They come from two different historical gallon definitions — the US fluid ounce is 1/128 of a US gallon, while the Imperial fluid ounce is 1/160 of an Imperial gallon, and the two gallons themselves are different sizes.
