The Spinervals web site has a conversion chart based on a scale of 1 to 5 as CA_in_NC has described. It's been updated since I was last there. There's also a pdf that compares standard and compact cranks as well as has the 1-5 scale. Pretty nifty little chart! I just downloaded it for future reference. Oh another vote for Mental Toughness and Tough Love. I think I just like Tough in the title.
