revolution per hour | Show source$\frac{revolution}{h}$ | revolution/h | 3600 | Revolutions per hour. See RPM unit for more. $\dfrac{\text{1 rotate}}{3600s} = \dfrac{1}{3600} Hz$ |

revolution per minute | Show source$\frac{revolution}{min.}$ | revolution/min. | 60 | Revolutions per minute. See RPM unit for more. $\dfrac{\text{1 rotate}}{60s} = \dfrac{1}{60} Hz$ |

revolution per second | Show source$\frac{revolution}{s}$ | revolution/s | 1 | Revolutions per second. See RPM unit for more. $\dfrac{\text{1 rotate}}{s} = 1 Hz$ |

revolution per minute | Show source$RPM$ | RPM | 60 | Revolutions per minute. The unit determines the number of turns (i.e. by 360 degrees) performed during one minute. It's a unit of rotational speed or the frequency of rotation around a selected axis. Used for example to measure speed of media under the read head e.g. gramophone disks rotates at speed 16 2⁄3, 33 1⁄3, 45 or 78 RPM. $1 RPM = \dfrac{1}{60s} = \dfrac{1}{60} Hz$ |

# Some facts

**Frequency**is**physical quantity**defining**number of cycles**(events occurring periodically)**per time unit**.- The
**basic frequency unit**in**SI system**is**one Hz**(hertz). One hertz corresponds to the frequency of**one cycle per second**:

$1 Hz = \dfrac{1}{s}$ - Frequency is usually indicated by a lower case letter
*f*or greek letter $\nu$ (nu). - To calculate the frequency of an event directly from the definition, use the following formula:

$f = \dfrac{n}{t}$where:

**f**- frequency,

**n**- number of recorded events (cycles),

**t**- measurement time.

- We can find
**frequency**in many everyday areas of life, e.g.

- The musical note of "A" is used as a standard for tuning musical instrument. It's frequency is 440 Hz. In terms of music, the lower frequency means "lower pitch".

- The
**processor**i5 2450M is available in versions**clocked**with frequencies**from 2.5 to 3,1 GHz**,

- the plates in most contemporary
**hard drives**make**5400 revolutions per minute**(5400 RPM),

- long play
**vinyl record**(LP) should be played at**33 1/2 revolutions per minut**(RPM),

**program 1 of Polish Radio**can be listened in Poland and in neighboring countries on longwave (LW) at**frequency 225 kHz**,

**wifi**networks use electromagnetic waves with**2,4 GHz**or**5 GHz**frequency,

**CD-AUDIO format**uses sample rating of**44,1 kHz**,

- the frequency of
**alternating current**(AC) is**50 or 60 Hz**depending on the region,

- etc.

- The musical note of "A" is used as a standard for tuning musical instrument. It's frequency is 440 Hz. In terms of music, the lower frequency means "lower pitch".

# How to convert

**Enter the number to field "value"**- enter the NUMBER only, no other words, symbols or unit names. You can use dot (**.**) or comma (**,**) to enter fractions.

Examples:- 1000000
- 123,23
- 999.99999

**Find and select your starting unit in field "unit"**. Some unit calculators have huge number of different units to select from - it's just how complicated our world is...**And... you got the result**in the table below. You'll find several results for many different units - we show you all results we know at once. Just find the one you're looking for.
