Yeah that's the rule of thumb I used after first moving here, but having now climbed here quite a bit I can say with some certainty that it's not perfectly accurate. I'd say that generally speaking 10c is about 21, 10d 22, and 11a 23, at least in California (which tends to have stiffer grades than some other states).

If anyone's in town and wants to double check my results I'd be happy to show them around some of the local crags!

[edit] Oh and of course 5.9 is all over the shop. I seem to recall a detailed post from Olbert on the topic a year or so ago.
