Common in US recipes for drinks and sauces - double-check it's fl oz (volume).
mL to Fluid Ounces Converter
Quick explanation
Use this converter when measurements are in mL and you need fluid ounces for US recipe steps or labeled containers. It is common when working between metric kitchen tools and US recipe references, or when you want to compare a metric bottle size with a US recipe or nutrition label. This matters with cream cartons, drink bottles, broth packages, and measuring jugs that show mL while the recipe or label discussion uses fluid ounces. One milliliter equals about 0.0338 US fluid ounces, so the numbers can feel less intuitive without a direct converter. This page gives exact values and practical guidance so conversions stay consistent while scaling, portioning, or comparing package sizes. It is also useful when you want to translate a metric amount into the volume language used on many US labels or menus without confusing fluid ounces with weight ounces in shopping, prep, or recipe notes. For reverse conversion, open fluid ounces to mL.

About these units
Millilitre (mL)
mL is the standard metric volume unit on many measuring tools and ingredient labels. It is precise, easy to scale, and common on metric packaging.
- 1000 mL = 1 L.
- mL is useful for precise volume control in recipes.
- Metric labels often stay in mL even when recipes switch to US units.
Fluid ounce (fl oz)
Fluid ounces are widely used in US recipes and beverage measurements. They are practical for US cups, bottles, and pouring references, but they still describe volume rather than weight.
- 1 US fl oz ≈ 29.5735 mL.
- fl oz is volume, not weight.
- 8 US fl oz is about 1 US cup.
Tips
When baking matters, weigh ingredients; volume can vary with packing and humidity.
Common reference: 8 US fl oz ≈ 236.6 mL (close to 1 US cup).
