Chapter 2.1 Notes
Name:
Converting Between Imperial Units:
Example One: In the 2008 Superbowl, Giant’s quarterback Elli Manning kept his team’s season alive by
completing an improbable 32 yard pass to David Tyree.
1) How long was this 32 yard pass in feet?
Hint: 3 feet = 1 yard
Solution:
2)
How long was this 32 yard pass in inches?
Hint: 1 yard = 3 feet
1 foot = 12 inches
Solution:
Example 2: Tiger Woods, in 2008, made an incredible 12 foot putt to force a playoff at the 2008 US
Open Championship.
1) How many inches was Tiger’s 12 foot putt?
Hint: 1 foot = 12 inches
2) The longest putt Tiger has made on tour is 91.5 feet long. How many yards was this 91.5 foot
putt?
Hint: 1 yard = 3 feet
Solution:
Example 3:
1) How many yards are in 108 inches?
Hint: 1 yard = 3 feet
1 foot = 12 inches
2) How many feet are in 18 inches?
Hint: 1 foot = 12 inches
Practice Problems:
Common abbreviations: Feet (ft. or ‘), Yard (yd.), and inches (in. or “).
1. Express the measurement in the units given:
a) 34 ft. = _________________ yd.
b) 98 inches = __________ ft.
c) 45’ = _________________ “
d) 4.5 yd. = ______________ in.
e) 1 mi. = ________________ ‘
f) 1 mi. = __________________ in.
(Hint: 1 mi. = 1760 yd.)
Converting Multiple Imperial Measurements
Example One: LeBron James, a star basketball player, has a height of 6 ft. 8 in. (6’ 8”). How many total
inches high is LeBron James?
Solution:
Example Two: What is 3 mi. 5 yd. 6 in. in ft.?
Hint: 1 mi. = 1760 yd.
Solution:
Practice Problems:
1. a) 3’ 11” = _____________ in.
c) 1 mi. 34 yd. 12 in. = ______________ ft.
b) 3 yd. 24 in. = ______________ ft.
d) 2 yd. 4 ft. 13 in. = ______________ in.
Adding & Subtracting Imperial Measurements:
Adding
a)
4’ 6” + 6’ 10” =
b) 12’ 3” + 4’ 9” =
Subtracting
a) 50’ – 12’ 7” =
b) 23’ 3” – 6’ 4”

Practice Problems: Leave each answer in inches.
1. a) 12’ 3” + 3’ 7” =
2. a) 60 ft. – 12’ 5”
b) 3’ 6” + 5’ 5” =
b) 1 yd. 3 ft. – 12 ft. 6 in.
