If you look through the code from here you'll most likely find what you're looking for.

nop, i looked up google groups and apis, but nothing... i need a algorithm for translating the mercator projection on to a rectangular grid....

still no luck....

The project I linked to has the code necessary to achieve what you want if you dig through it. All google maps projects must ultimately convert a lat/long to an x/y or else they wouldn't be able to display tiles
