Understanding Milliliters and Fluid Ounces
Before learning how many ounces are in 250 ml, it helps to understand the two units. A milliliter (ml) is part of the metric system and is used in most countries worldwide. It measures the volume of liquids such as water, milk, juice, and cooking oil.
A fluid ounce (fl oz) measures liquid volume in the US customary and Imperial systems. Although both are called fluid ounces, they are not exactly the same size. That is why how many ounces are in 250 ml depends on whether you are using US or UK measurements.
