ODE uses whatever system you want -- and the gravity is in the same 
system. If you feed it feet, stone and swatch beats, then acceleration 
will be expressed in feets per swatch beats squared.

Usually, most people use SI units (meters/seconds/kilograms) but you're 
free to re-define the units as you see fit -- as long as they are 
internally consistent.
