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.
