What does 'oz' stand for?

The abbreviation 'oz' stands for ounce, which is a unit of weight commonly used in both the United States customary and British imperial systems. One ounce is equivalent to one-sixteenth of a pound or approximately 28.35 grams. Ounces are often used for measuring ingredients in cooking and baking, as well as in nutrition labels to indicate serving sizes for food products.

Understanding this unit is essential in various medical and nutritional contexts, where precise measurements can impact patient care and dietary recommendations. Each of the other options represents different units of measurement: quart is a larger liquid capacity, teaspoon is a smaller volume measurement, and Celsius is a temperature scale, all of which are unrelated to the abbreviation 'oz'.
