If you've taken physics, the real help comes in the fact that the 
majority of units are some multiple of other units with no other factors 
to throw in (and thus, misremembered at times).

For example, one Watt (unit of power) is equal to one Joule (unit of 
energy) per second.  One horsepower (imperial unit of power) is equal to 
some silly number of foot-pounds per second.
