If an equivalent relationship between the given units and the desired units cannot be found in the
conversion tables, multiple conversion factors must be used. The conversion is performed in several
steps until the measurement is in the desired units. The given measurement must be multiplied by each
conversion factor (ratio). After the common units have been canceled out, the answer will be in the
desired units.
Example:
Convert 2.91 sq miles to sq meters.
Step 1.
Select the equivalent relationship from the conversion table. Because there is
no direct conversion shown for square miles to square meters, multiple
conversions will be necessary. For this example the following conversions will
be used.
sq miles to sq yds to sq ft to sq m
1 sq mile = 3.098 x 10 sq yd
6
1 sq yd = 9 sq ft
10.764 sq ft = 1 sq m
Step 2.
Express the relationship as a ratio (desired unit/present unit).
Step 3.
Multiply the quantity by the ratio.
Step 4.
Repeat the steps until the value is in the desired units.
