What cup holds 8 ounces?

There isn't one specific cup that *always* holds 8 ounces. Here's why:

* "Cup" can be ambiguous: It can refer to a standard measuring cup (which is usually 8 ounces), or it can refer to a drinking cup, which comes in many sizes.

* Different types of ounces: There are fluid ounces (fl oz) and weight ounces (oz). Most recipes use fluid ounces, so a "cup" in that context is likely 8 fl oz.

To be sure, always check the container:

* Measuring cups: Look at the markings. Most standard measuring cups will clearly indicate "1 cup" or "8 fl oz".

* Drinking cups: These vary greatly. Read the label or check online for the specific cup you're using.

Here's a helpful tip: If a recipe calls for a "cup," it almost always means an 8-ounce measuring cup.
