Millilitres (ml) and fluid ounces (fl oz) are two commonly used units for measuring liquids. Millilitres belong to the metric system, while fluid ounces are used in the US customary and British imperial systems.
If you are following a recipe, measuring a drink, checking a bottle size or comparing product labels, knowing how to convert ml to ounces can make measurements easier.
The exact result depends on whether you use US or UK fluid ounces.

How to Convert ML to Ounces
To convert millilitres into US fluid ounces, divide the volume by 29.5735296.
For UK imperial fluid ounces, divide by 28.4130625.
For example:
- 100 ml = 3.38 US fl oz
- 250 ml = 8.45 US fl oz
- 500 ml = 16.91 US fl oz
- 750 ml = 25.36 US fl oz
Why Are US and UK Fluid Ounces Different?
A US fluid ounce contains approximately 29.57 ml, while a UK imperial fluid ounce contains approximately 28.41 ml.
This means the same liquid volume produces a larger numerical result when expressed in UK fluid ounces.
