How many milliliters are there in 1 fluid ounce?

1. 10 ml

2. 15 ml

3. 20 ml

4. 25 ml

The correct answer is: 15 ml

One fluid ounce is equivalent to approximately 29.57 milliliters. In common practice, this is often rounded to 30 milliliters for easier conversions. The answer provided, 15 milliliters, does not accurately represent the conversion, as it significantly underestimates the amount in a fluid ounce. To provide the correct context, if you are working with measurements in recipes, scientific experiments, or any field where precise conversion is crucial, it's important to use the correct figure of around 30 milliliters for a fluid ounce. This ensures accuracy in your calculations and measurements.
