Customary Measurements
Length
12 inches (in)= 1 foot (ft)
3 feet = 1 yard (yd)
5,280 feet = 1 mile (mi)
Weight
16 ounces (oz) = 1 pound (lb)
2000 pounds = 1 ton
Capacity
8 fluid ounces (fl oz) = 1 cup (c)
2 cups = 1 pint (pt)
2 pints = 1 quart (qt)
4 quarts = 1 gallon (gal)

9. Additional Example 2A: Converting Customary Units

Additional Example 2A: Converting Customary Units
Convert 5,000 pounds to tons.
Method 1: Use a Proportion
Write a proportion using a ratio of equivalent measures.
pounds tons
2,000 1
5, m x =
Using Proportions
2,000 • x = 1 • 5,000
2000x = 5,000
x = 2.5
5,000 pounds is equal to 2.5 tons.

10. Additional Example 2B: Converting Customary Units

Additional Example 2B: Converting Customary Units
Convert 5,000 pounds to tons.
Method 2: Multiply by 1
Multiply by a ratio equal to 1, and cancel the units.
5,000 p m 1
1 ton t 2,000 p
5,000 p = 
Multiplying by 1 is the same as dividing by the number of pounds in 1 ton.
1 ton t 2,000
= 5,000 
= 2.5 tons
5,000 pounds is equal to 2.5 tons.

Method 1: Use a Proportion
Write a proportion using a ratio of equivalent measures.
cups pints
2 1
c 24 =
You have to know how many cups there are in 1 pint
1 • c = 2 • 24
c = 48
24 pints is equal to 48 cups.

Convert 24 pints to cups.
Method 2: Multiply by 1
Multiply by a ratio equal to 1, and cancel the units.
24 pt m1
2 ct 1 pt
24 pt = 
This is actually multiplying by 1 because 1 pint has 2 cups in it.
Multiplying by 2c over 1pt is the same as multiplying by 1 because 1 pint has 2 cups in it.
2 c 1
= 24 
= 48 cups
24 pints is equal to 48 cups.

Allison orders a 6-ounce grilled chicken sandwich. Dominic orders a quarter-pound grilled chicken sandwich. Which sandwich weighs more? Explain.
First convert a quarter-pound to ounces.
ounces pounds
16 1
x .25
Write a proportion using 16 oz = 1 lb. =
x = 4 oz
Allison’s sandwich weighs more because Dominic’s sandwich is only 4 oz.

Tedd and Fergie go the hardware store to purchase a bag of nails. Tedd buys a bag of nails that weighs 7 pounds 8 ounces. Fergie buys a bag of nails that weighs 128 ounces. Which bag of nails weighs more? Explain.
First convert 7 pounds to ounces.
ounces pounds
16 1
x 7
Write a proportion using 16 oz = 1 lb. =
x = 112 oz + 8 oz
x = 120 oz
Fergie’s bag of nails weigh more because Tedd’s bag only weighs 120 oz.
