The Milliliters to Fluid Ounces Converter converts volume from milliliters to both US and UK (imperial) fluid ounces. One US fluid ounce equals 29.5735295625 mL, while one UK fluid ounce equals 28.4130625 mL.
This conversion is one of the most commonly needed in cooking, bartending, medicine, and cosmetics. Recipes from different countries use different volume systems — metric (mL) vs US customary (fl oz) vs UK imperial (fl oz) — and the difference between US and UK fluid ounces adds another layer of complexity.
A US fluid ounce is about 4% larger than a UK fluid ounce. While this difference is small for individual measurements, it compounds in larger quantities and can affect recipes, medication dosing, and product labeling. Our converter shows both simultaneously to prevent confusion.
Results also include US cups for cooking convenience, since many American recipes measure ingredients by the cup.
The formulas: US fl oz = mL ÷ 29.5735295625 and UK fl oz = mL ÷ 28.4130625. For US cups: cups = mL ÷ 236.588 (since 1 US cup = 8 US fl oz = 236.588 mL). The US fluid ounce is defined as 1/128 of a US gallon, while the UK fluid ounce is 1/160 of a UK gallon.
Common references: a standard shot = 44.36 mL (1.5 US fl oz), a can of soda = 355 mL (12 US fl oz), a water bottle = 500 mL (16.9 US fl oz), and a wine bottle = 750 mL (25.36 US fl oz).

100 mL = 3.381 US fl oz = 3.520 UK fl oz.
1 US fl oz = 29.5735 mL.
1 UK fl oz = 28.4131 mL — slightly smaller than a US fl oz.
They derive from different gallon definitions. The US fl oz = 1/128 US gallon (29.57 mL), the UK fl oz = 1/160 UK gallon (28.41 mL).
1 US cup = 236.588 mL. 1 UK cup = 284.131 mL. 1 metric cup (Australia) = 250 mL.
250 mL is approximately 1.06 US cups or exactly 1 metric cup (used in Australia and some international recipes).
Divide mL by 14.787 for US tablespoons. 1 US tablespoon = 14.787 mL.
500 mL = 16.907 US fl oz ≈ a standard water bottle.
A standard US shot = 44.36 mL (1.5 fl oz). A UK shot = 25 or 35 mL depending on the establishment.
Yes, 1 mL = 1 cc (cubic centimeter) for practical purposes. They are equivalent units of volume.
