About This Milliliters to Fluid Ounces Converter
The milliliter (mL) is the metric unit of liquid volume, used globally on beverage labels, medical dosing instructions, and recipe measurements. The fluid ounce (fl oz) is the US customary unit for the same purpose, appearing on every American beverage bottle, medicine bottle, and cosmetic container. One US fluid ounce equals exactly 29.5735 mL. Note that the UK fluid ounce (28.413 mL) differs slightly — this converter supports both.
This converter supports seven volume units: milliliters, US fluid ounces, UK fluid ounces, liters, US cups, tablespoons, and teaspoons. Home cooks scaling international recipes, travelers comparing beverage sizes across countries, and pharmacists verifying liquid medication dosages across metric and imperial labels all use this conversion throughout their day.

When You Need to Convert Milliliters to Fluid Ounces
Beverage comparisons are the most frequent use case. A European 330 mL can of sparkling water is 11.15 fl oz — smaller than a standard US 12 fl oz (355 mL) can. A 500 mL bottle is 16.9 fl oz, which is why US water bottles are sold as "16.9 oz" — the metric volume printed on the back of the label is the primary measurement, and the fl oz is derived from it.
Skincare and cosmetics labeling requires both units in many markets. A 100 mL face serum must also show "3.38 fl oz" on packaging sold in the US. TSA liquid rules for carry-on luggage allow containers of 3.4 fl oz (100 mL) — knowing this equivalence prevents confiscated toiletries at security checkpoints. A 75 mL bottle (2.54 fl oz) is compliant; a 120 mL bottle (4.06 fl oz) is not.
Cooking and baking across international recipes is the third major driver. A French recipe calling for 200 mL of cream requires 6.76 fl oz, which is just under 7 fl oz — easy to measure with a US measuring cup that has fl oz markings. A British recipe specifying 150 mL of milk is 5.07 fl oz. Knowing these values prevents the common mistake of using a full cup (8 fl oz / 237 mL) when the recipe calls for something smaller.
