mL to oz Converter Calculator
Convert between milliliters and fluid ounces in seconds. This calculator handles both US fluid ounces (29.57 mL) and imperial fluid ounces (28.41 mL), so you always get the right measurement for your recipe, medication, or lab work.
Milliliters and fluid ounces are the two most common units for measuring small liquid volumes. The tricky part is that US and imperial fluid ounces are not the same size.
Key Conversion Factors:
- 1 US fluid ounce = 29.5735 mL
- 1 imperial fluid ounce = 28.4131 mL
- 1 mL = 0.03381 US fl oz
- 1 mL = 0.03520 imp fl oz
Common mL to US Fluid Ounce Conversions:
| Milliliters | US Fluid Ounces | Common Use |
|---|---|---|
| 5 mL | 0.169 fl oz | 1 teaspoon |
| 15 mL | 0.507 fl oz | 1 tablespoon |
| 30 mL | 1.014 fl oz | Shot glass |
| 240 mL | 8.115 fl oz | 1 US cup |
| 355 mL | 12.0 fl oz | Soda can |
| 500 mL | 16.907 fl oz | Water bottle |
| 750 mL | 25.361 fl oz | Wine bottle |
| 1000 mL | 33.814 fl oz | 1 liter |
Why the difference matters: If you follow a British recipe that calls for 5 fl oz and measure with a US fluid ounce cup, you will end up with about 4% more liquid than intended. For baking, that can throw off the result.
