The table rounds for quick reading; use the calculator for more displayed precision. A US fluid ounce differs from an imperial fluid ounce. For a recipe measured in teaspoons, use the mL to US teaspoons converter.
This calculator converts milliliters to US fluid ounces. It uses 1 US fluid ounce = 29.5735295625 mL and does not treat a mass ounce as a fluid ounce.

Keep fluid ounces separate from scale ounces
The output is US fluid ounces rather than weight ounces. Retain a bottle’s volume and a scale reading as separate quantities. Comparing their masses requires density in addition to this volume conversion.
