Basic to the understanding of unit conversion is the understanding equivalence, the understanding of the multiplicative identity of 1, and how the two are related. For a review of these concepts, click on Review.

Review the following table (Webster's New World Dictionary, Second Edition, Simon and Schuster, 1982) of Standard Units of Conversion to see if you can create fractions that have a value of 1. You can click to examples following each table.



Example 4: Convert 100 meters to miles.


Method 1: Convert meters to feet to miles in one step.



Method 2: Convert meters to decameters to hectometers to kilometers to miles.
