This calculator converts liquid volumes from US fluid ounces (fl oz) to milliliters (ml) using the standard conversion factor. It is a useful tool for anyone needing to switch between US customary and metric volume units.
What is an Ounces to Milliliters Calculator?
An Ounces to Milliliters (oz to ml) Calculator is a tool used to convert liquid volume measurements from US fluid ounces (fl oz) to milliliters (ml). This conversion is frequently needed in cooking, medicine, chemistry, and any field where precise liquid measurements are critical and may involve different unit systems.
US fluid ounces are part of the US customary system, while milliliters are a unit of volume in the metric system. Accurate conversion between these units is essential for international recipes, scientific experiments, and correct medication dosages.
Ounces to Milliliters Formula
The conversion from US fluid ounces to milliliters is based on the standard definition:
1 US fluid ounce (fl oz) = 29.5735 milliliters (ml)
Therefore, to convert fluid ounces to milliliters, you multiply the number of fluid ounces by 29.5735:
Milliliters (ml) = Fluid Ounces (fl oz) × 29.5735
Where:
- Milliliters (ml) = Volume in milliliters
- Fluid Ounces (fl oz) = Volume in US fluid ounces
How to Calculate Ounces to Milliliters: Example
Imagine you have a recipe that calls for 4 US fluid ounces of juice, and you need to measure it in milliliters.
- Identify the amount in fluid ounces:
Fluid Ounces = 4 fl oz
- Apply the conversion formula:
Milliliters = Fluid Ounces × 29.5735
Milliliters = 4 × 29.5735 = 118.294 ml
So, 4 US fluid ounces is approximately equal to 118.29 milliliters.
Common Applications
- Cooking and Baking: Converting recipes from US customary units to metric units.
- Medicine and Pharmaceuticals: Measuring liquid medication dosages accurately.
- Chemistry and Laboratories: Preparing solutions and conducting experiments requiring precise volume measurements.
- Beverage Industry: Standardizing packaging and serving sizes across different regions.
- Travel: Understanding liquid allowances for carry-on luggage which are often specified in ml.
