8. Use Math Tools The approximate metric
measurement of length is given for a U.S. customary
unit of length. Use your estimation skills to complete
the graphic organizer below. Fill in each blank with
foot , yard, inch, or mile.
SOLUTION: Compare the metric measures in the table with the
customary measures.
Centimeter is a small unit of measure, so 1 inch
would be about 2.54 centimeters.
I know that a meterstick is about 3 feet, so 0.30
meter would be approximately 1 foot.
1 meter is about 3 feet and 3 feet is equal to 1 yard,
so 0.91 meter is about 1 yard.
A kilometer is a large unit that often represents a city
block. So, 1.61 kilometers is about 1 mile.
