RPM

Turns per minute

RPM stands for revolutions per minute, a unit measuring rotational speed.

In automotive contexts, higher RPM means the engine is working harder: Don't redline the RPM.

The abbreviation also appears in industrial machinery specifications and audio equipment. (Lowercase rpm is the same abbreviation, often preferred in technical writing.)
