Understanding the Conversion from Milliliters to Fluid Ounces
Milliliters (ml) and fluid ounces (fl oz) are two widely used units of volume. While milliliters belong to the metric system, fluid ounces are part of the U.S. customary and British imperial systems. Converting between ml and oz is essential when working with international recipes, medical dosages, beverage packaging, and scientific measurements.
What Is a Milliliter (ml)?
A milliliter is a metric unit of volume equivalent to one-thousandth of a liter. It is commonly used worldwide in cooking, pharmacy, science, and everyday life. Because it is based on the decimal system, the milliliter is easy to use in calculations and widely adopted in international standards.
What Is a Fluid Ounce (oz)?
A fluid ounce is a unit of volume used primarily in the United States and formerly in the UK. In the U.S., 1 fluid ounce equals approximately 29.5735 milliliters. In the UK, the fluid ounce is slightly smaller at around 28.413 ml. This calculator uses the U.S. fluid ounce standard.
