Inches vs. centimeters
If you express your height both in inches and in centimeters, which unit gives the larger number for your height?
A. The result in centimeters is larger because you are comparing your height to a unit of length smaller than the inch.
B. Your height in inches is a larger number because an inch is larger than a centimeter.
C. Both approaches give the same number because your height does not depend on the unit used to express it.
Suppose you had a ruler just 1 cm long. To measure the height of a 5-ft-tall person, you would have to move the ruler end to end up the person’s body about 150 times. However, if your ruler were 1 in.
long, you would have to move it just 60 times (5 ft = 60 in). Thus, the smaller your unit of measure, the larger the number you will get when you measure something with it. The correct answer is A.
