  2. Conversion Factors Every Conversion Factor can be Written Three Different Ways epw 9/17/2008

  3. Convert Miles to Kilometers Given 1 in. = 2.54 cm epw 9/17/2008

  4. Convert Miles to Kilometers Given 1 in. = 2.54 cm Calculate how many cm are in 1 foot epw 9/17/2008

  5. Convert Miles to Kilometers Given 1 in. = 2.54 cm Calculate how many cm are in 1 foot 1 ft = 12 in. epw 9/17/2008

  6. Convert Miles to Kilometers Given 1 in. = 2.54 cm Calculate how many cm are in 1 foot 1 ft = 12 in. 1 ft = 12 in. x 2.54 cm 1 in. epw 9/17/2008

  7. Convert Miles to Kilometers Given 1 in. = 2.54 cm Calculate how many cm are in 1 foot 1 ft = 12 in. 1 ft = 12 in. x 2.54 cm = 30.48 cm 1 in. epw 9/17/2008

  8. Convert Miles to Kilometers Given 1 in. = 2.54 cm Calculate how many cm are in 1 foot 1 ft = 12 in. 1 ft = 12 in. x 2.54 cm = 30.48 cm 1 in. 1 mile = ???? ft epw 9/17/2008

  9. Convert Miles to Kilometers Given 1 in. = 2.54 cm Calculate how many cm are in 1 foot 1 ft = 12 in. 1 ft = 12 in. x 2.54 cm = 30.48 cm 1 in. 1 mile = 5280 ft epw 9/17/2008

  10. Convert Miles to Kilometers • Given 1 in. = 2.54 cm • Calculate how many cm are in 1 foot • 1 ft = 12 in. • 1 ft = 12 in. x 2.54 cm = 30.48 cm 1 in. • 1 mile = 5280 ft x 30.48 cm ft epw 9/17/2008

  11. Convert Miles to Kilometers • Given 1 in. = 2.54 cm • Calculate how many cm are in 1 foot • 1 ft = 12 in. • 1 ft = 12 in. x 2.54 cm = 30.48 cm 1 in. • 1 mile = 5280 ft x 30.48 cm = 160934.4 cm ft epw 9/17/2008

  12. Convert Miles to Kilometers • Given 1 in. = 2.54 cm • Calculate how many cm are in 1 foot • 1 ft = 12 in. • 1 ft = 12 in. x 2.54 cm = 30.48 cm 1 in. • 1 mile = 5280 ft x 30.48 cm = 160934.4 cm ft • Now convert 160934.4 cm to km epw 9/17/2008
