Ml To Oz Conversion Calculator
Accurate liquid measurement is essential in cooking, baking, pharmaceuticals, science experiments, and even skincare formulations. If you often find yourself needing to convert milliliters (ml) to fluid ounces (fl oz), our Ml to Oz Calculator makes the process quick, simple, and precise.
Whether you're following a recipe from another country or measuring liquid ingredients for professional use, this calculator instantly converts milliliters into:

No manual math. No confusion. Just accurate results in seconds.
Why Convert Ml to Oz?
Milliliters (ml) are part of the metric system, commonly used worldwide. Fluid ounces (fl oz), however, are used mainly in the United States and the United Kingdom. The tricky part?
US and UK fluid ounces are not the same.
- 1 US fluid ounce = 29.5735 ml
- 1 UK fluid ounce = 28.4131 ml
Because of this difference, using the wrong conversion can lead to inaccurate measurements — especially in recipes or medical dosing.
That’s why our calculator provides both US and UK fluid ounce results, eliminating guesswork completely.
