Conversions
-Refer to SI Prefixes and Conversion factors to guide us to find the answer
-One note to help you, it is to always remember a given value with a variable x, and when you multiple the conversion factor, the variable x must be the denominator so then you can cross the "like" factors
For ex./ Convert 8 cm to m
8 cm X 1m/ 100cm, so then the cm is crossed out because it is the same variable.
the answer is 0.08 m or 5 X 10 to the power of -2.
For more info, go to this youtube video, it might help you better to understand the Unit Conversions and hot to do them: 
P.S. You will have to memorize this chart!
BUT.... You only have to remember all of the except...yotta, zetta, exa, peta, yocto, zepto, atto, ferto. So that's not a lot to memorize!
