Unit Analysis

Unit Analysis – writing the units when comparing each unit of rate

One technique for converting customary units of measure is by multiplying by a unit multiplier. The next slide will show you how this is done.

For example, to convert 412 feet into yards: First, write 412 feet over 1. Next, multiply by the unit multiplier, which in this case would be 1 yard . 3 feet 412 feet x 1 yard = 1 3 feet 412 yards 3 feet will cancel leaving your answer with the correct label!

Now you try it!

Convert 412 feet to inches. 412 feet 1 First, write 412feet over 1 . Next write the unit multiplier. Make sure that feet is in the denominator! 12 inches 1 foot Multiply the rate and conversion factor together. 412 feet x 12 inches = 1 1 foot 4944 inches
