To convert US Fluid Ounces to Milliliters, multiply the value by 29.5735. This factor comes from the ratio of the two units' definitions: one US Fluid Ounce equals 29.5735 Milliliters.
For example: 1 US Fluid Ounce = 29.5735 Milliliters, and 10 US Fluid Ounces = 295.735 Milliliters.
To convert in the reverse direction — from Milliliters to US Fluid Ounces — multiply by 0.033814.
The fluid ounce (fl oz) is a unit of volume — distinct from the mass ounce — and it comes in two incompatible versions that cause significant confusion in international cooking and bartending. The US fluid ounce is approximately 29.5735 mL, while the imperial fluid ounce (used in the UK and some Commonwealth countries) is approximately 28.4131 mL, making the US version about 4.1% larger. A US pint of 16 fl oz thus contains 473 mL, while a UK pint of 20 imperial fl oz contains 568 mL.
Despite this international confusion, the fluid ounce is ubiquitous in US food and beverage contexts. Bottled water in the US is sold in 8 fl oz, 16.9 fl oz, and 33.8 fl oz sizes; a standard US coffee mug holds 8–12 fl oz; and cocktail recipes in American bar guides specify quantities in fluid ounces (or fractions thereof, since jiggers and shot glasses are calibrated in fluid ounces). US food labeling specifies volumes in fluid ounces alongside milliliters.
The relationship of the fluid ounce to mass is only approximate. A fluid ounce of water weighs almost exactly one avoirdupois ounce at room temperature — a convenient but accidental coincidence — but a fluid ounce of oil, milk, or alcohol has a different mass. This is why recipes should not substitute fluid ounce measurements for mass ounce measurements: a fluid ounce of flour and a weight ounce of flour are not the same amount.
The milliliter (mL) is one thousandth of a liter, and is exactly equal to one cubic centimeter (cm³ or cc). This equivalence — one of the most useful in the metric system — means that a milliliter of water weighs almost exactly one gram at room temperature, connecting volume, length, and mass in a single elegant relationship. The milliliter is the standard unit for small liquid volumes in science, medicine, and everyday cooking throughout the metric world.
Medical dosing is almost universally expressed in milliliters: a teaspoon of cough syrup (5 mL), an insulin injection (a few tenths of a milliliter), an IV drip rate (mL per hour). Syringes are calibrated in milliliters, and the accuracy of dosing — critical for drugs with narrow therapeutic windows — depends on reading milliliter markings correctly. Blood test tubes typically hold 2–10 mL of sample.
In the kitchen, milliliters replace teaspoons and tablespoons in precise cooking and baking. A standard espresso shot is 30 mL; a typical yogurt serving is 150 mL; a wine glass holds 150–250 mL. Carbonated drinks are sold in 250 mL, 330 mL, 355 mL (a US 12 fl oz can), 500 mL, and 750 mL bottles — a range that neatly illustrates how the milliliter accommodates both personal servings and larger quantities.
