Narrative:

We were assigned 17;000. ATC gave us a climb to FL180; which we initiated. As we began to level at the transition altitude; ATC questioned our altitude. At this point we were leveling and we went to standard. The altitude ballooned to around 18;200 due to the pressure difference. The call from ATC was confusing at first; but we immediately corrected when we realized the problem.the book says the move to standard should be done climbing through the transition altitude and it states (18;000); if the pressure difference is great by the time you reach 18;000 you may have already deviated from the assigned altitude. In the future I think I would go to standard a little earlier perhaps 17;500 and be mindful of the barometric change.

Title: EMB170 First Officer reported being level at 17;000 feet then assigned FL180 by ATC. The altimeter is not reset to 29.92 until reaching 18000 feet resulting is a 200 foot overshoot.
