How many milliliters are in one fluid ounce?

One fluid ounce is equivalent to approximately 28.41 milliliters. This conversion is based on the standardized measurements used in both the U.S. customary system and the metric system. Knowing this conversion is useful for a variety of practical applications, such as cooking, where measurements are often needed in different units, and for accurate dosing in medicinal preparations.

When you consider the other options, the value 14.21 ml does not represent a common conversion from fluid ounces, and 227.00 ml significantly exceeds the actual volume of a fluid ounce. Additionally, 158.99 liters is an entirely inappropriate unit in this context, as it is unrealistic when compared to fluid ounces, which deal with much smaller volumes. Understanding the relationship between these units can help ensure accurate measurements in various trades and disciplines.
