Milliliters to Fluid Ounces Converter

The milliliter-to-fluid-ounce conversion is essential in bartending, cooking, medicine, and cosmetics — any context where small liquid volumes appear in both metric and US customary units. This converter uses US fluid ounces (1 US fl oz = 29.5735 ml). In bartending and cocktail recipes, spirits and liqueurs are measured in milliliters outside the US and in fluid ounces (commonly called just "ounces") in US bar culture. A standard US jigger is 1.5 fl oz (44.36 ml). A European recipe calling for 30 ml of gin is 1.01 fl oz — essentially 1 fl oz in US bar measurement. The double is 2 fl oz = 59.15 ml. For medications, US liquid prescriptions are sometimes dispensed in fluid ounces, while the underlying dosing is calibrated in milliliters. Cough syrup dosage labels may say "take 10 ml" or "take 2 teaspoons" (1 US teaspoon = 4.93 ml). Children's medicine doses in the US switch between teaspoons and ml depending on the product. In cosmetics, products sold globally list volume in ml; US products may add fl oz. A 100 ml bottle of fragrance is 3.38 fl oz — the standard 3.4 fl oz (100 ml) limit for carry-on liquids on flights aligns these two units. Wine pours: a standard US pour is 5 fl oz (147.9 ml); the standard European pour is often 150 ml (5.07 fl oz) — very close but technically different.
