Two formulas that I've used in the past:

EER SEER approximately equal to 0.9 * SEEREER
EER = -0.02SEER^2 + 1.12SEER

The first is just from general googling, and was a rough consensus value between several sources. The second is from the eQuest mailing list forums. Using a SEER of 10 gives you 9 from the first, and 9.2 from the second.
