Customary units of weight are measurement units commonly used in the United States to measure how heavy objects are. The main units are ounces, pounds, and tons.
Weight measures how heavy something is, while mass measures the amount of matter in an object. On Earth, we often use these terms interchangeably.
Customary weight units relate to each other through specific conversion factors that never change.
