A barometric pressure reading of 29.92 inches mercury is commonly known as "standard pressure". Below 18,000ft, local altimeter settings are used because you need to know how high you are above terrain, or whether or not you're at the proper altitude for an instrument approach, or at pattern altitude, etc. In cruising flight above 18,000ft, except for a few places in the world, you are well above any terrain, so errors in actual altitude of even a couple thousand feet is unlikely to cause a problem.
When you're "up in the flight levels" and away from squishing those bugs, now that's the big time.
