60 Hz equals 3600 RPM.
Converting frequency from hertz (Hz) to revolutions per minute (RPM) involves multiplying the Hz value by 60, because there are 60 seconds in a minute and each cycle corresponds to one revolution. So, 60 Hz means 60 cycles per second, which results in 3600 revolutions per minute.

Conversion Formula
The formula to convert frequency in hertz (Hz) to revolutions per minute (RPM) is RPM = Hz * 60. This works because one hertz equals one cycle per second, and there are 60 seconds in a minute, so multiplying Hz by 60 gives the number of revolutions per minute. For example, 1 Hz equals 60 RPM, 2 Hz equals 120 RPM, and so on.
Conversion Example
- Convert 45 Hz to RPM:
- Multiply 45 by 60, because RPM = Hz * 60.
- 45 * 60 = 2700 RPM.
- So, 45 Hz is 2700 RPM.
- Convert 75 Hz to RPM:
- 75 * 60 = 4500 RPM.
- Thus, 75 Hz equals 4500 RPM.
- Convert 90 Hz to RPM:
- 90 * 60 = 5400 RPM.
- Therefore, 90 Hz is 5400 RPM.
- Convert 30 Hz to RPM:
- 30 * 60 = 1800 RPM.
- So, 30 Hz equals 1800 RPM.
- Convert 15 Hz to RPM:
- 15 * 60 = 900 RPM.
- Hence, 15 Hz is 900 RPM.

Conversion Definitions
Hz (Hertz)
Hz, or hertz, measures how many cycles or vibrations happen in one second, indicating the frequency of periodic events like waves or rotations, with 1 Hz meaning one cycle per second.
RPM (Revolutions Per Minute)
RPM counts how many complete turns or revolutions an object makes in one minute, used to specify rotation speed of engines, turbines, and disks, providing a measure of how fast something spins or rotates.
Conversion FAQs
How accurate is the conversion from 60 Hz to RPM?
The conversion from Hz to RPM is exact when applying the formula RPM = Hz * 60, assuming the frequency measurement is precise. Variations may occur due to measurement errors or device-specific factors but the calculation itself remains accurate.
Can I use this conversion for alternating current (AC) motors?
Yes, the Hz to RPM conversion applies to AC motors because their rotation speed directly correlates with the frequency of the power supply, assuming the motor is synchronous, meaning it rotates at a speed matching the frequency.
What happens if the frequency changes in a motor running at 60 Hz?
If the frequency increases or decreases, the RPM will change proportionally, because RPM = Hz * 60. This means a higher frequency results in a faster rotation, while a lower frequency causes slower movement, affecting performance and efficiency.
Is the formula different for asynchronous motors?
For asynchronous (induction) motors, the actual RPM typically runs slightly below the synchronous speed calculated by RPM = Hz * 60, because of slip. The formula gives the theoretical maximum speed, not the exact operating speed.
Does this conversion work for non-rotational systems?
No, the conversion specifically applies to rotational systems where cycles per second relate directly to revolutions. For linear or non-rotational movements, different formulas are used.
