Which abbreviation corresponds to ounce?

Which abbreviation corresponds to ounce?

• A. lb
• B. oz
• C. gr
• D. T or tbsp

Answer: (B)

Ounce is abbreviated oz. This shorthand is used for the avoirdupois ounce, a unit of mass. In practice, 1 pound equals 16 ounces, so ounces are the smaller part of a pound. The other abbreviations refer to different units: lb stands for pound, gr stands for grain (a tiny weight used historically), and T or tbsp stands for tablespoon, a unit of volume. When working with dosages, it's important to note whether you're measuring weight or volume and to convert correctly between units, for example using 1 lb = 16 oz or 1 oz ≈ 28.35 g.
