The web page you refer to says this:

  velocity units: Angstroms per 1/20.455 ps

This is *not* what you wrote above. The velocites give the number of
Angstroms travelled in (roughly) 50 fs, not 20 ps.

[The unit of length in Amber is Angstroms; the unit of time is 1/20.455 ps.
Velocities have units of length/time.]
