Measuring Weight in the US Customary System of Measurement

This video tutorial explains the US customary system of measurement, focusing on weight. It contrasts the US system with the metric system, highlighting the differences in unit consistency and conversion ease. The tutorial clarifies the concepts of mass and weight, noting that weight is influenced by gravity, unlike mass. It introduces the US customary units of weight: pounds and ounces, and provides everyday object comparisons for better understanding. The video also addresses common confusions between weight and volume ounces, emphasizing the distinction with the term 'fluid ounce'.

Which system of measurement is primarily used in the United States?

• Metric System

• US Customary System

• International System

• Imperial System

What is the main difference between mass and weight?

• Weight is affected by gravity, mass is not

• Weight is constant, mass varies

• Mass changes with location, weight does not

• Mass is measured in pounds, weight in kilograms

Why do scientists prefer using the term mass over weight?

• Weight is more precise

• Mass is consistent and does not change

• Mass is easier to measure

• Weight is not affected by gravity

How many ounces are there in one pound?

• 10

• 8

• 16

• 12

What is a common misunderstanding about the ounce unit?

• It is used only for weight

• It is the same as a gram
