What Is a Fluid Ounce?
A fluid ounce is a way to measure how much liquid something carry. People mostly use fluid ounces in the United States and the United Kingdom when they cook, drink, or buy things like juice or shampoo. One fluid ounce is a little less than two tablespoons. In the U.S., one fluid ounce equals about 29.57 millilitres. In the U.K., it’s a bit less, about 28.41 millilitres. So when you see “fl. oz.” on a bottle or recipe, it’s telling you how much liquid is inside using this unit.
What Is a Millilitre (mL)?
A millilitre, or mL in short, is a small unit used to measure liquid. It is a part of the metric system, which is used in most countries around the world like in Asia and in UK/European countries. One millilitre is about the same as a few drops of water. There are 1,000 millilitres in one liter. You’ll often see millilitres on drink bottles, medicine labels, and in science class. It helps people know exactly how much liquid they are using or taking.Ounces to Millilitres Conversion Chart
