Rpm (disambiguation) Guide, Meaning , Facts, Information and Description
rpm or RPM may mean:
- An acronym for 'revolutions per minute', rpm is a unit of frequency, commonly used to measure rotational speed.
- Gramophone (phonograph) records typically rotate at 16, 33 1/3, 45, or 78 rpm (CAV).
- Audio CD rotation rates vary from about 500 rpm when reading the innermost CD track, to 180 rpm when reading tracks near the outer edge (CLV).
- An automobile's engine typically makes between 700 and 7000 rpm.
- Aircraft piston motors can rotate with 8000 rpm.
- A racing car engine's limits are much higher, as high as 19,000 rpm in Formula One.
- Gas turbine engines rotate at tens of thousands of rpm.
- A computer's hard drive can range from 3000-7200 RPM on IDE types and from 10-25,000 on SATA and SCSI drives.
- A 52x CD-ROM drive can rotate a cd as fast as 32,000 RPM.
The SI unit of frequency is the hertz (Hz):
- 1 rpm = 1 r/min = 1/60 Hz
- The SI unit of angular speed is the radian per second:
- rotational speed = 1 rpm = 1 r/min ( = 1/60 Hz) = 2π rad/min = 2π/60 rad/s = 0.104 719 76 rad/s = angular speed
- RPM:
- RPM Package Manager (originally called "Red Hat Package Manager")
- RPM (movie)
- RPM (band), a Brazilian rock band
- In firearms, Rounds Per Minute: how many shots an automatic weapon can fire in one minute
- On roads in the United States, RPM stands for Raised Pavement Marker.
