1. Customary and Metric Measurements
Objective: Students identify and convert customary and metric units of measure.

2. Common Equivalent Customary Units
Length
Capacity
12 inches (in)= 1 foot (ft)
8 fluid ounces (fl oz) = 1 cup (c)
3 feet = 1 yard (yd)
2 c = 1 pint (pt)
5,280 ft = 1 mile (mi)
2 pt = 1 quart (qt)
1,760 yds= 1 mi
4 qt = 1 gallon (gal)
Weight
16 ounces (oz) = 1 pound (lb)
2,000 lbs = 1 ton

3. 19 cups is equal to 152 fluid ounces
Try This!!!
Convert 19 c to fl oz
Method 1: Proportions Write a proportion
Method 2: Multiply by 1 Multiply by a ratio equal to 1 and divide out the units
19 cups is equal to 152 fluid ounces

4. Metric Units base on powers of 10
103=1,000
102=100
101=10
100=1

1/101=1/10=0.1
1/102=1/100=0.01
1/103=1/1000=0.001

To convert metric units, multiply or divide by a power of 10
Multiply to convert to smaller unit
Divide to convert to larger unit

5. Try This!!! Convert each measure. 510 cm to meters
2.3 L to milliliters
100 cm=1m
So divide by 100
1 L=100mL
So multiply by 1000
Move decimal 2 places left
Move decimal 3 places right

6. G-LaND 1-gallon (gal)= 4-quarts (qt)= 8-pints (pt)= 16-cups (c)=
128 ounces (oz)
8oz=1 cup

7. Example 1:
Convert 5,000 pounds to tons.

8. Example 2: Convert each measure. 530 cL to liters
1,070 g to milligrams

9. Example 3:
Addison buys one pumpkin that has a mass of 3 kg and another that has a mass of 2,150 g. Which pumpkin has the greater mass? How much greater is its mass?
