20 Hz converts to 1200 rpm.
This means that a frequency of 20 cycles per second is equivalent to 1200 revolutions per minute. To convert from Hz to rpm, multiply the Hz value by 60 because there are 60 seconds in a minute and each cycle corresponds to one revolution.
Conversion Process
Converting Hertz (Hz) to revolutions per minute (rpm) involves understanding how frequency relates to rotational speed. Since 1 Hz equals 1 cycle per second, and there are 60 seconds in a minute, multiplying Hz by 60 gives rpm. For example, 20 Hz times 60 equals 1200 rpm, indicating 20 cycles every second translate into 1200 revolutions per minute.

Conversion Formula
The formula to convert Hz to rpm is rpm = Hz x 60. This works because one Hz equals one cycle per second, and there are 60 seconds in a minute. Therefore, multiplying the Hz value by 60 converts the frequency into revolutions per minute. For example, at 20 Hz, the calculation is 20 x 60 = 1200 rpm.
Conversion Example
- Convert 10 Hz to rpm:
- Multiply 10 by 60.
- 10 x 60 = 600 rpm.
- So, 10 Hz equals 600 rpm.
- Convert 5 Hz to rpm:
- 5 x 60 = 300 rpm.
- Thus, 5 Hz corresponds to 300 rpm.
- Convert 30 Hz to rpm:
- 30 x 60 = 1800 rpm.
- Therefore, 30 Hz is 1800 rpm.

Conversion Definitions
Hz: Hertz measures the frequency of a repeating event per second, indicating how many cycles or oscillations occur in one second, used in waves, vibrations, and signals. One Hz equals one cycle per second.
RPM: Revolutions per minute quantifies how many complete turns a rotating object makes in one minute, used in motors, engines, and mechanical systems to specify rotational speed.
Conversion FAQs
What does 20 Hz correspond to in revolutions per minute?
20 Hz equals 1200 rpm because multiplying the frequency by 60 converts seconds to minutes, giving the number of rotations per minute.
Is the conversion from Hz to rpm the same for all types of machinery?
Yes, the conversion formula (Hz x 60) applies universally, but specific equipment may have different interpretations based on their design and operation.
Can I use this conversion for vibrations in structures?
Yes, vibrations at a certain Hz can be translated into rpm if the oscillations correspond to rotations, but often vibrations are linear and may not directly relate to rpm.
Why does multiplying Hz by 60 give rpm?
Because Hz is cycles per second, and there are 60 seconds in a minute, multiplying Hz by 60 converts the frequency into revolutions per minute.
What is the significance of converting Hz to rpm in engineering?
Converting Hz to rpm helps engineers understand how fast a machine or component rotates, which is crucial for design, safety, and performance assessments.
