How many milliliters in 1 fl oz?
1 fl oz = 29.57352956 ml. The other way round: 1 ml = 0.0338140227 fl oz. The US fluid ounce is 1/128 of a US gallon, 29.5735 ml; the imperial fluid ounce is slightly smaller (28.4131 ml). US cans and bottles are labelled in fl oz. A millilitre is one thousandth of a litre and exactly the same volume as one cubic centimetre (cm³).

How to use
- 1Pick a category — length, weight, temperature, volume, area, speed, data, time, pressure or energy.
- 2Choose the “from” and “to” units, or press swap to reverse them.
- 3Type a value in either field — the other side updates as you type.
- 4Adjust the decimal precision and check the conversion table for common values.
Exact conversion factors
Many imperial units are defined exactly in metric terms: 1 inch = 2.54 cm, 1 foot = 0.3048 m, 1 mile = 1.609344 km, 1 pound = 0.45359237 kg and 1 US gallon = 3.785411784 litres. The converter uses these definitions, so results are as precise as the decimals you choose to show. The formula is displayed in words — for example “multiply by 2.54” — so you can repeat the calculation by hand.
Temperature is different
Celsius, Fahrenheit and Kelvin do not share a zero point, so temperature cannot be converted with a single factor. °F = °C × 9/5 + 32 and °C = (°F − 32) × 5/9; Kelvin is Celsius + 273.15. That is why 0 °C is 32 °F, while a 10-degree change in Celsius is an 18-degree change in Fahrenheit.
US vs UK units and data sizes
A US gallon (3.785 L) is smaller than an imperial UK gallon (4.546 L), and US fluid ounces differ slightly from UK ones — check which system your recipe or spec uses. For data sizes, storage makers use decimal units (1 GB = 1,000 MB), while operating systems often count in binary units (1 GiB = 1,024 MiB), which is why a new drive shows less capacity than the label.
Frequently asked questions
