How Much Is 16 Oz? Weight and Volume Guide
What Is an Ounce?
An ounce is a small unit of measurement used for weight or volume. In the United States, two common types exist:
- Weight ounce (avoirdupois ounce) – measures mass. It equals about 28.35 g.
- Fluid ounce (fl oz) – measures volume of liquids. One US fluid ounce is roughly 29.57 ml.
Most people encounter ounces when buying food, drinks, or when a recipe calls for a specific amount.
Fluid Ounce vs. Weight Ounce
The two ounce types are not interchangeable. Mixing them up leads to errors in cooking, science, and shipping.
- Use fluid ounces for liquids such as water, milk, or oil.
- Use weight ounces for solids like flour, sugar, or meat.
- A 16 fl oz bottle does not weigh the same as 16 oz of honey.
