Enter volume in fluid ounces and select ounce type to convert to milliliters.
Note: This calculator converts fluid ounces to milliliters using standard conversion factors (1 US fl oz ≈ 29.5735 ml, 1 UK fl oz ≈ 28.4131 ml). US fluid ounces are used in the United States, while UK fluid ounces are used in the UK, Canada, Australia, and some other countries. Results are rounded to two decimal places. Ensure the input is a positive number for accurate results.
Converting between ounces and milliliters is a common task in cooking, bartending, medicine, and other fields where precise liquid measurements are essential. Ounces, specifically fluid ounces, are a unit of volume in the imperial system, primarily used in the United States, while milliliters are a metric unit used globally. This guide provides a clear explanation of the conversion process, including the formula, a step-by-step method, a conversion chart, and specific conversions for commonly queried values like 1 ounce to milliliters or 8 ounces to milliliters. It also addresses conversions for specific liquids like water and answers frequently asked questions such as “Is 30 mL the same as 1 oz?” or “How much is 8 oz in ml?” The focus is on fluid ounces (fl oz), as this is the standard for liquid measurements, unless otherwise specified.
A fluid ounce (fl oz) is a unit of volume in the US customary and imperial systems, used to measure liquids. In the US, 1 fluid ounce equals exactly 29.5735295625 milliliters. The UK imperial fluid ounce, less commonly used, equals approximately 28.4130625 milliliters. This guide focuses on the US fluid ounce unless otherwise noted, as it’s the most prevalent in recipes and everyday use. A fluid ounce differs from a weight ounce (used for mass), so context is key when measuring.
A milliliter (ml) is a metric unit of volume, equal to one-thousandth of a liter or one cubic centimeter (cm³). It’s widely used worldwide for precise measurements in cooking, medicine, and science, often marked on measuring cups, syringes, or bottles. The metric system’s base-10 structure simplifies scaling: 10 ml = 1 centiliter, 100 ml = 1 deciliter, 1,000 ml = 1 liter. Also check this Cups to Milliliters Converter.
Converting ounces to milliliters (or milliliters to ounces) is straightforward with the correct conversion factor:
Identify the ounce type: For US fluid ounces, use 29.5735295625 ml per ounce. For UK imperial fluid ounces (less common), use 28.4130625 ml.
Apply the formula:
Example: Convert 8 US fluid ounces to milliliters: 8 × 29.5735295625 = 236.5882365 ≈ 236.588 ml.
The formulas for conversion are:
US Fluid Ounces to Milliliters: Milliliters = Fluid Ounces × 29.5735295625
Milliliters to US Fluid Ounces: Fluid Ounces = Milliliters ÷ 29.5735295625
UK Imperial Fluid Ounces to Milliliters: Milliliters = Fluid Ounces × 28.4130625
For most applications, the US fluid ounce is standard. Example: 500 ml to US fluid ounces = 500 ÷ 29.5735295625 ≈ 16.907 fl oz. also use this Gallons to Liters Conversion.
This chart provides conversions for common US fluid ounce values to milliliters, rounded to 3 decimal places, addressing terms like “ounce to milliliter chart” or “ounces to milliliter conversion chart”:
| Fluid Ounces (US) | Milliliters (ml) |
|---|---|
| 1 fl oz | 29.574 |
| 2 fl oz | 59.147 |
| 8 fl oz | 236.588 |
| 12 fl oz | 354.882 |
| 16 fl oz | 473.176 |

Water, with a density of 1 g/ml at standard temperature, converts directly by volume. Example: 1 US fl oz of water = 29.5735295625 ml ≈ 29.574 ml. The conversion is the same for any liquid (e.g., juice, oil) as fluid ounces and milliliters measure volume, not weight.
For liquids like milk, cream, or oil, the conversion is identical to water because fluid ounces and milliliters are volume-based. Example: 8 US fl oz of milk = 236.588 ml. Density only matters when converting to grams (e.g., 1 fl oz water = 29.5735295625 grams, but 1 fl oz oil ≈ 27.3 grams due to lower density).
Below are conversions for frequently queried values, using US fluid ounces, rounded to 3 decimal places unless otherwise noted:
