How to Convert Revolution Per Minute to Hertz

1 revolution per minute = 0.0166667 hertz exact

Hertz = Revolution Per Minute × 0.0166667

Example: 120 rpm × 0.0166667 = 2 Hz

Reverse Conversion

To convert hertz back to revolutions per minute:

  • Remember, 1 hertz equals 60 revolutions per minute.
  • To convert 2 Hz to rpm, multiply 2 x 60, resulting in 120 rpm.

exact This conversion factor is exact by international definition.
