Converting Measurements

  1. 1. Converting measurements Using the dimensional analysis method.
  2. 2. Theory behind the process <ul><li>Multiply a measurement by “one.” </li></ul><ul><li>The “one” is an equivalence factor that has the same value in the numerator as in the denominator. </li></ul><ul><li>Example 12 inches or 1 foot </li></ul><ul><li>1 foot 12 inches </li></ul><ul><li>Multiplying by one keeps the value of the measurement the same but uses different units. </li></ul>
  3. 3. Convert 21.2 miles/gallon to feet/cup. <ul><li>21.2 mi x 5280 ft x 1 gal x 1 qt x 1 pt </li></ul><ul><li>1 gal 1 mile 4 qts 2 pts 2 c </li></ul><ul><li>= 6996 ft/cup </li></ul>
  4. 4. Notice how each label is cancelled by the same label in a different position. The positioning of the label determines the multiplication or division with the numbers. <ul><li>21.2 mi x 5280 ft x 1 gal x 1 qt x 1 pt = </li></ul><ul><li>1 gal 1 mile 4 qts 2 pts 2 c </li></ul><ul><li>6996 ft/cup </li></ul>
  5. 5. Reflection <ul><li>This measurement could be about mileage for a car. </li></ul><ul><li>The conversion of 21.2 miles per gallon to 6996 ft per cup means the car could go over a mile on one cup of gasoline. </li></ul><ul><li>This might not be practical on a dark and stormy night. </li></ul>
