Why is it called U.S Customary Units of Weight?(3 votes)- Because units change in every country in the world. For example, in Japan, people don't use inches!(2 votes)
What is the difference between weight and mass?(1 vote)- Weight and mass are used interchangeably, but they don't mean the same thing.
Mass is the amount of matter in an object, while weight is the force of gravity by which the earth attracts towards it.
So your mass on Jupiter and Earth would be the same, but your weight would be different. But in math levels right now, you can use them interchangeably.(6 votes)
