## What could be done is to ask it at [PhysicsSE][1]. 
That would improve the location of the question, however, you'd likely get down voted there for lack of research, since it doesn't take much of an internet search to convert units to arrive at the equation set up and you then plug in the values. 
 Someone at RPGSE was kind enough to do that for you.
