How to Convert Revolution Per Minute to Hertz

1 revolution per minute = 0.0166667 hertz exact

Hertz = Revolution Per Minute × 0.0166667

Example: 1800 rpm × 0.0166667 = 30 Hz

Reverse Conversion

To convert hertz back to revolutions per minute:

  • Remember, 1 hertz equals 60 revolutions per minute.
  • To convert 30 Hz to rpm, multiply 30 x 60, resulting in 1800 rpm.

exact This conversion factor is exact by international definition.

1,800 RPM equals 30 Hz — the synchronous speed of a 4-pole AC motor on 60 Hz power (North America). Standard for many industrial pumps and fans.

1800 rpm is also equal to:

  • 0.03 kilohertz
About these units

Revolution per minute: Unit of rotational frequency; number of complete revolutions per minute.

Hertz: SI unit of frequency; one cycle (or event) per second. Symbol: Hz = s⁻¹
