What is a Glassful?

A "glassful" is a unit of measurement that is equal to one glass or container filled with a liquid. It is often used to measure the amount of liquid contained in a glass or container, such as a glass of water or a glass of juice.

For example, if you have a glass that holds 8 ounces of liquid, you could say that it is full of water up to the brim, and that it contains a glassful of water. Similarly, if you have a pitcher that holds 4 cups of liquid, you could say that it is half full of juice, and that it contains two glassfuls of juice.

The term "glassful" is often used in recipes or when describing the amount of liquid in a container. It is a convenient way to measure the amount of liquid in a glass or container without having to use a measuring cup or other precise measurement tool.
