Activity 8-2: Measurement Conversions
Name:
There are several different ways to convert between units of measurement. One very good way
is to use proportions.
Example
14 gallons = x qt.
Use the fact that 1 gal = 4 qt.
Example #2
14 qt. = x gal.
1 gallon x gallons

4 quart 14 quarts
1  14 4 x

4
4
3.5 gal  x
1 gallon 14 gallons

4 quart
x quarts
1  q  4  14
q  56 quarts
A conversion factor is a ratio of two equivalent measurements. Since the two measurements in a
conversion factor are equivalent, a conversion factor is equal to 1.
Example While weight lifting, John adds 11.35 kilograms to his bar. About how many pounds
does he add to his bar?
1 pound  0.454 kilograms
To complete the conversion multiply the kilograms by the conversion factor.
11.35 kg 
1 lb
 25 pounds
0.454 kg
Putting multiple conversion factors together is called dimensional analysis. This method will
better prepare you for advanced math and science classes in the future.
Example
14 gallons = x qt.
14 gallons 4 quarts

 56 quarts
1
1 gallon
Let’s say you want to convert 55 miles per hour to feet per second.
Example #2
55 miles 5280 feet 1 hour 1 min. 80.7 ft.




1 hour
1 mile
60 min. 60 sec. 1 sec.
The units cancel each other out leaving just feet per second left. This tells you that your answer
is in the correct units.

Which weighs more: an ounce of water or an ounce of lead?
Surprise! The water weighs more because it is measured by volume, while lead is measured by
weight. If you set a cup with a fluid ounce of water on a balance scale across from an ounce of
lead in an identical cup, the scale will tip toward the water.
