RPM usually stands for Revolutions Per Minute. Typically you'll find it on motorized vehicles where it tell you how fast the crankshaft of the engine is turning. Knowing the crankshaft speed can be useful, as too fast can damage the engine. The engine is also most fuel efficient in a certain range, so the RPMs can tell you when you should change gears.
