Conversions and Dimensional Analysis A.K.A. Factor-Label

Conversions Ratio of equivalent measurements

Dimensional Analysis… What is it? Converting a known quantity into an unknown quantity using conversion factors Using units to help you get to the answer Steps: What is the known/given quantity? What is the unknown quantity? What conversion factors do I know to help?

Example How many yards are equivalent to 75 inches?

Practice Convert 5.5 km to m. Convert 3.4 x107 mg to kg.

Complex Conversions Convert 75 m/sec to km/min. Convert 42.1 cm3 to m3.

Practice with Complex Conversions Convert 15 m/sec to km/hr. Convert 12 m3 to mm3.

Practice! Convert 43nm to km. Convert 31g/L to kg/cm3. Convert 40cm3 to m3.
