r.p.m. is an abbrevation for revolutions per minute. it tells us about the revolution speed of the engine. it is generelly multiplied by 1000 as shown in various gauges

The instrument measuring the RPM is the tachometer, commonly mounted side by side with the speedometer. It measures the spinning speed of the engine flywheel, i.e. revolution per minute. A high RPM does not meant you are travelling at a high speed all the times.
Cheer!

RPM = revolutions per minute
On the gauge in your vehicle, multiply the numbers x 1000 to find out actually how many rpm's your engine is turning.

Revolutions Per Minute

Everyone seems to have answered your question...
You will notice that RPM's start to raise as you increase your speed.... once you change gears (manually, or if your automatic tranny does it for you) you will notice that the RPM's drop down... and then start to raise again when you accelerate
If you didnt change gears, your RPM's would keep increasing.. most engines can only handle 5000-8000 RPM's
SOOO.. if you didnt change gears, your engine would be working so hard it would destruct.....
Also... Horse power normally reaches its peak at the highest RPM... Torque normally gives you power when your RPM's are low... So, you need to learn your car to figure out where your 'RPM sweet-spot' is....
Horse power is 'how fast you will hit a wall'
Torque is 'how far you will go through the wall'

Revolutions Per Minute, how fast a motor is going, e.g. A push bike rider averages about 100 revolutions per minute, formula 1 cars push their engine revolutions to 12,000+ rpm. normal auto engines from idle (500 rpm) to going hard (4,500 rpm).RPM is a measurement of cyclic speed

RPM is Revolutions per minute.
1000 RPM's is 1000 revolutions of the crankshaft of the engine.

Revolutions per minute. But it measures the speed in which the drive shaft turns (enigines themselves don't typically turn). This motion is then transfered to the wheels to make the car move.
One note about RPMs, this is more of a measure of how hard the engine is working at any given point more than it is a measure of actual speed.

RPM stands for revolutions per mimute which is what your engine does. That lets you know how revolutions pem minute your engine is turning over.
