The conversion of 20 Hz to RPM is 1200 RPM. This is because 1 Hz equals 60 RPM, so multiplying 20 by 60 gives the result.
In detail, since frequency in Hertz (Hz) measures cycles per second, and RPM (revolutions per minute) counts how many times something spins in a minute, converting between them involves multiplying the Hz value by 60 because there are 60 seconds in a minute. Therefore, 20 Hz equals 20 times 60 RPM, which is 1200 RPM.
Conversion Result
20 Hz is equivalent to 1200 RPM. This conversion shows how many rotations per minute correspond to a frequency of 20 cycles per second.

Conversion Formula
The formula to convert Hz to RPM is RPM = Hz × 60. This works because Hz measures the number of cycles per second, and there are 60 seconds in a minute, so multiplying Hz by 60 gives the rotations per minute. For example, for 20 Hz: 20 × 60 = 1200 RPM.
Conversion Example
- Convert 10 Hz to RPM:
- Step 1: Take the Hz value, which is 10.
- Step 2: Multiply by 60 to convert to RPM: 10 × 60 = 600 RPM.
- Result: 10 Hz equals 600 RPM.
- Convert 5 Hz to RPM:
- Step 1: Hz value is 5.
- Step 2: 5 × 60 = 300 RPM.
- Final answer: 5 Hz equals 300 RPM.
- Convert 0.5 Hz to RPM:
- Step 1: Hz value is 0.5.
- Step 2: 0.5 × 60 = 30 RPM.
- Result: 0.5 Hz equals 30 RPM.

Conversion Definitions
Hz: Hertz (Hz) measures the number of cycles, vibrations, or oscillations that occur in one second, representing frequency, used in electronics, sound, and mechanical systems.
RPM: Revolutions per minute (RPM) quantifies how many complete turns or rotations a rotating object makes in one minute, used in engineering and machinery to measure rotational speed.
Conversion FAQs
Can I convert any Hz value to RPM using the same formula?
Yes, the conversion formula RPM = Hz × 60 applies to all frequency values, regardless of how high or low they are, as long as the system’s rotation is uniform and continuous.
Why does multiplying Hz by 60 give RPM?
This is because 1 Hz equals 1 cycle per second, and there are 60 seconds in a minute, so multiplying by 60 converts cycles per second to cycles per minute, which is RPM.
Is the conversion accurate for all types of rotational systems?
While the formula is mathematically correct, actual RPM may vary depending on the mechanical system’s efficiency, slippage, or other factors. The conversion gives a theoretical RPM based on frequency alone.
How do I convert a frequency of 15 Hz to RPM?
Multiply 15 by 60: 15 × 60 = 900 RPM. This indicates that at 15 Hz, the system rotates 900 times per minute.
What happens if the frequency is negative in Hz?
Negative frequency is not physically meaningful in typical rotation contexts; it might represent phase or direction in wave systems but doesn’t correspond to a physical RPM value.
