Convert milliliters to fluid ounces and other volume units instantly. Accurate metric-to-imperial volume conversion for cooking, science, and everyday use.
A standard 355 mL soda can.
In fluid ounces: 12.0 fl oz
Calculation: 355 mL × 0.033814 = 12.0 fl oz
This is the standard 12 oz soda can size found in the US.
A typical bottled water serving.
In fluid ounces: 16.9 fl oz
Calculation: 500 mL × 0.033814 = 16.9 fl oz
The common 16.9 fl oz water bottle found in convenience stores.
A cup-equivalent of cooking oil for recipes.
In fluid ounces: 8.45 fl oz
In cups: 1.06 cups
250 mL is slightly more than 1 US cup (236.588 mL).
A 1 L carton of milk.
In fluid ounces: 33.8 fl oz
In cups: 4.23 cups
1 L = 33.814 fl oz. Recipes often call for 4 cups (which is ~946 mL, slightly less than 1 L).
Understanding how to convert between milliliters (mL), fluid ounces (fl oz), liters (L), and cups is essential for cooking, science experiments, medication dosing, and international travel. Our converter uses the following standard conversion factors.
| Milliliters (mL) | Fluid Ounces (fl oz) | Cups (US) |
|---|---|---|
| 1 mL | 0.034 fl oz | 0.004 cup |
| 10 mL | 0.338 fl oz | 0.042 cup |
| 50 mL | 1.691 fl oz | 0.211 cup |
| 100 mL | 3.381 fl oz | 0.423 cup |
| 250 mL | 8.454 fl oz | 1.057 cup |
| 500 mL | 16.907 fl oz | 2.113 cup |
| 1 L (1000 mL) | 33.814 fl oz | 4.227 cup |
1 cup = 236.588 mL ≈ 8 fl oz. When cooking, rounding to 240 mL per cup is common for ease.
A standard water bottle is 500 mL (16.9 fl oz). The daily recommended intake is about 2 L (67.6 fl oz) — roughly 4 bottles.
TSA allows liquids up to 100 mL (3.4 fl oz) per container in carry-on baggage. This is approximately ⅓ of a standard soda can.
When scaling recipes between metric (mL) and imperial (fl oz), use our converter to ensure accurate measurements for consistent results.
Converting milliliters (mL) to fluid ounces (fl oz) is a common need when working with recipes, scientific measurements, or comparing product volumes across different measurement systems. The metric system uses milliliters and liters, while the US customary system uses fluid ounces and cups.
The fundamental conversion factor is: 1 milliliter = 0.033814 fluid ounces. To convert any value in milliliters to fluid ounces, simply multiply the number of milliliters by 0.033814. For example, 250 mL × 0.033814 = 8.45 fl oz — slightly more than one cup (which is 8 fl oz or 236.588 mL).
For reverse conversions (fluid ounces to milliliters), multiply by 29.5735. This means a 12 fl oz soda can contains approximately 355 mL. Understanding these conversions is especially useful when following international recipes, measuring medication doses, or tracking hydration goals across different unit systems.
It's important to note that the US fluid ounce (29.5735 mL) is slightly different from the UK imperial fluid ounce (28.4131 mL). Our calculator uses the US customary fluid ounce, which is the standard used in the United States for food labeling, cooking, and beverage measurements. If you need imperial conversions, divide the milliliter value by 28.413 instead.
Volume conversion between milliliters and fluid ounces is essential in many everyday situations:
Many international recipes use metric measurements while US recipes use cups and ounces. Our converter helps you seamlessly switch between systems for perfect results every time.
Liquid medications are often measured in milliliters, but dosing instructions may reference teaspoons or ounces. Accurate conversion is critical for safe medication administration.
Scientific experiments require precise volume measurements. Converting between metric and imperial units ensures accurate reagent preparation and data reporting.
When shopping, products may be labeled in mL (imports) or fl oz (domestic). Our converter helps you compare prices and quantities across different labeling systems.
⚠️ Important Note: This Milliliter to Ounce Converter is for informational and practical purposes only. While we strive for accuracy, always verify critical measurements (such as medication doses or scientific experiments) using certified measuring equipment. Conversion factors are based on US customary units and may differ from imperial (UK) measurements. Always check which system your product or recipe uses.
