"units" [ http://en.wikipedia.org/wiki/Units_(Unix) ] is your friend

  $ units
2445 units, 71 prefixes, 33 nonlinear units

You have: 1 rydberg/bohrradius^3
You want: gigapascal
	* 14710.505
	/ 6.7978632e-05

With the Ubuntu version, at least, using "au" instead of "bohrradius" 
produces interesting results.  It helps to read the documentation.
