How is it calculated, and what does it mean?

Maybe this (http://en.wikipedia.org/wiki/Gear_inches) will help.

Oh, I get it now.

More gear inches=stiffer gear. Hence the constant penis size comparison jokes. Coolbeans, thanks for the link.

In the context of fixed-gear, what is a reasonable GI for a reasonably in-shape person (but one who has been riding with gears and has never ridden FG.)?

So 42x16 or 44x17 would be good noob gears?

Yea, I was going to say anything from 60-80 depending on elevation changes.

If you have access to a geared bike, try it out there. 42x16/17 is pretty common.
