True, after you do the calculation, but initself not a very helpfull number.
In this case, its sort of an intermediate step in a calculation, rather than
a usefull result in itself.  Also kind of confusing.

Only after you remenber the units of measure that are to be used in the
equation.  An exaple WITH UNITS does help a lot.
