You can't directly translate.  Old visions were squares, while new ones 
are circles.  For small vision radiuses it does translate easily but for 
large ones you can only approximate.  Best way to approximate is to 
square it and multiply by two.  1 becomes 2, 2 becomes 8.  Anything 
larger you should play around with to get the radius you want.
