Can someone translate this igh's gear ratio % into sprocket teeth?

And if possibke,how does that change if I change the driven sprocket?
==============================

Might check with the website directly for Sturmey Archer:

http://www.sturmey-archer.com/

http://www.sturmey-archer.com/products/hubs 3 speeds don't show that part, but maybe call or email for the info.... the place that selling your link though is in Somerset UK, shipping is probably not worth it to USA though see about exchange rate and return policy

Here is a link from Sheldon Brown that shows a hub and the ratios in percent:

ARDMORE,OK
Thanks for the links. I'm pretty sure I got it now,just kept getting the runaround at first. And now I'm going with a nexus inter-3. I think. The problem I was having is these are for the rear wheel,not a mid-drive. Doesn't mean it can't be used that way though.
