Fluid Ounces vs. Ounces: Know the Difference
By Shumaila Saeed || Published on February 28, 2024
Fluid ounces measure volume, often used for liquids; ounces measure weight, used for both solids and liquids.
Key Differences
Fluid ounces are a unit of volume used primarily to measure liquids. It quantifies the space that a liquid occupies. Ounces, on the other hand, are a unit of weight, used to measure the mass of an object or substance. Both units are used in everyday measurements but represent different physical properties.

The use of fluid ounces is common in recipes and on beverage containers, indicating the volume of liquid present. Ounces are often seen on packaging to denote the weight of a product, whether it's food, mail, or raw materials. While fluid ounces are exclusively for volume, ounces have a broader application in measuring weight.
