Usage

What does fl. oz. mean? Fl. oz. is an abbreviation of fluid ounce (or fluid ounces), a unit used in the measurement of the volume of liquids. An ounce is a unit used in the measurement of weight. (Both ounce and ounces can be abbreviated as oz.) A fluid ounce is used to measure volume (capacity), not weight—specifically, the volume of a fluid (liquid). In everyday conversation, the word ounces is often used instead of saying fluid ounces, as in I just drank 16 ounces of that energy drink. The abbreviation oz. is sometimes used in this way, as in a 20 oz. bottle of water. You’ll often see the abbreviation fl. oz. (or fl oz, without the periods) on the labels of containers that contain liquid or some other kind of non-solid, such as a can of soda or a bottle of moisturizer, to indicate how much stuff the container contains. It is also seen in recipes. Fluid ounces are used in the United States Customary System and the British Imperial System of measurement. In the Customary System, there are 8 fluid ounces in a cup and 16 fluid ounces in a pint. There are 20 fl. oz. in an Imperial pint. A fluid ounce is equal to 29. 57 milliliters (1 milliliter is equivalent to 0. 033815 fl. oz.)Example: Standard soft drink cans contain 12 fl. oz., but they also sell 8 oz. cans.
