Unit Conversion
Example 1
Airam is driving at 70 miles per hour, what is her approximate speed in kilometers per hour?


1 pound x
=
16 ounces 80 ounces

How to convert one unit of measurement to another.
Terms & Names:
Rate: a comparison of two quantities that have different units of measure
Speed: distance divided by time
Unit: a particular amount of length, time, etc., that is used as a standard for counting or measuring
Per: indicates rate
Convert: to express a given measurement in terms of a different unit of measurement
Ratio: comparison of two numbers of quantities, may be written as a fraction
How to set up this problem
1 mile 70 miles
1.6 km = x hours


Check for Understanding
By Azzel Menzie, Airam Lopez, Nathalie Mejia
When you're given a measurement in one unit, and you are asked to change it to a different unit, you can make a conversion by setting up a proportion
Customary
12 inches = 1 foot
3 feet = 1 yard
1760 yards = 1 mile
Temperature
Fahrenheit: 9/5 celsius + 32
Celsius: 5/9 fahrenheit - 32
Metric

10 millimeter=1 centimeter
100 centimeters=1 meter
100 meters=1 kilometers
Time
60 seconds = 1 minute
60 minutes = 1 hour
24 hours = 1 day
7 days = 1 week
Write
rate of
conversion
as fraction
Miles
Airam is
driving at
what you're trying
to figure out
1 mile 70 miles
1.6 km = x hours
Cross
multiply
}
1 x X = 1.6 x 70
1x = 112
x = 112 kilometers
}
Solve
for x
A bag of Skittles weighs 80 ounces. How heavy is the bag in pounds?
1 pound = 16 ounces
Answer:
x = 5 pounds
( 1 mile is approximately equal to 1.6 kilometers )
cross multiply
}
16x = 1 x 80
16x = 80
x = 5 lbs
Basic Units
Common Misconception
Many times people forget to line up the same units with each other
Correct:
1 foot x
x
12 inches 50 inches
Nat bought a desk that measures 50 inches long, how much is this in feet?
Incorrect:
1 foot 50 inches
x
12 inches x
A little more challenging. . .
Azzel took a 3 hour nap, how much is this in seconds?
1 hour = 60
1 minute = 60 seconds
1 hour 3 hours
x
60 minutes x

First
Convert hours to minutes
x = 60x3
x = 180 minutes
1 minute 180 minutes
x
60 seconds x
Then convert minutes to second
x = 180x60
x= 10,800
Azzel slept for 10,800 seconds
