To change from smaller units to larger units, divide.

5. Ounce (fl oz) Cup (c) Pint (pt) Quart (qt) Gallon (gal) Inch (in)
1. Divide to go down
2. Multiply to go up
Ounce (fl oz)
Cup (c)
Pint (pt)
Quart (qt)
Gallon (gal)
Inch (in)
Foot (ft)
Yard (yd)
Mile (mi)
Second (s)
Minute (min)

8. 2 mi = ? ft Feet are smaller than miles; so multiply!
Example 1:
2 mi = ? ft
Feet are smaller than miles; so multiply!
2 x 5280 = 10,560 ft

9. 5 pt = ? c Cups are smaller than pints; multiply! 2 x 5 = 10 cups
Example 2:
5 pt = ? c
Cups are smaller than pints; multiply!
2 x 5 = 10 cups

10. Example 3:
The elevator in an office building has a weight limit posted of one and a half tons. How many pounds can the elevator safely hold?
1 ton = 2,000 pounds

11. Pounds are smaller than tons; multiply!
1 ½ x 2,000 = 3,000 pounds

12. 1,000 in = ? ft Feet are larger than inches; Divide!
Example 4:
1,000 in = ? ft
Feet are larger than inches; Divide!
1,000 ÷ 12 = 83 1/3 feet

13. 6 qt = ? gal Gallons are larger than quarts; Divide!
Example 5:
6 qt = ? gal
Gallons are larger than quarts; Divide!
6 ÷ 4 = 1 ½ gallons
