Well, I think the most accurate figure for the expansion (Hubble's constant) is currently around 75 km per second per kiloparsec. Just look up a few conversion factors and report back to us how that converts into cm/sec per micron or whatever. :^)
But while local gravity would swamp the effect, it seems that the expansion would have some very, very small effect on the "force" of gravity -- slowing gravity's effect by an impreceptible amount. This may not be true, however, at the atomic level with the electromagnetic force, which operates by set amounts of quanta. There is no "in between" one quantum and another, so the expansion would not only be "swamped" by the EM force, but it would also be prohibited from having ANY effect.
