I created a chart to help you understand the relationship between ounces, cup, pints, quarts, and gallons. These units are used in the United States in order to measure volume.
Volume is a measure of how much space an object takes up.
This video will help with the following standard,
CCSS.Math.Content.5.MD.A.1

You may enjoy this " How to Convert " course which shows how to convert within the same units.
