150 Hz equals 9000 rpm.
To convert 150 Hz to rpm, multiply the frequency in hertz by 60 because there are 60 seconds in a minute and rpm measures rotations per minute. So, 150 Hz * 60 = 9000 rpm, meaning at 150 cycles per second, the object rotates 9000 times each minute.
What is the conversion from Hz to RPM?
The conversion from Hz to rpm involves multiplying the frequency in hertz by 60. This is because Hertz measures cycles per second, and rpm measures rotations per minute. The formula is: rpm = Hz * 60. For example, if you have 10 Hz, then rpm = 10 * 60 = 600 rpm. This works because each cycle in Hz corresponds to a rotation, and there are 60 seconds in a minute, so you scale up accordingly.

Conversion Formula
The formula to convert Hz to rpm is rpm = Hz * 60, because one Hz equals one cycle per second, and there are 60 seconds in a minute. Multiplying the Hz value by 60 converts cycles per second into rotations per minute. For example, 1 Hz equals 60 rpm, 2 Hz equals 120 rpm, and so on. This formula is based on basic unit conversions, where each cycle in Hz corresponds exactly to one rotation, and the factor 60 scales seconds to minutes.
Conversion Example
- Convert 200 Hz to rpm:
- Step 1: Take the Hz value, which is 200 Hz.
- Step 2: Multiply by 60: 200 * 60 = 12000.
- Step 3: Result: 200 Hz equals 12000 rpm.
- Convert 75 Hz to rpm:
- Step 1: Take the Hz value, which is 75 Hz.
- Step 2: Multiply by 60: 75 * 60 = 4500.
- Step 3: Result: 75 Hz equals 4500 rpm.
- Convert 50 Hz to rpm:
- Step 1: Take the Hz value, which is 50 Hz.
- Step 2: Multiply by 60: 50 * 60 = 3000.
- Step 3: Result: 50 Hz equals 3000 rpm.

Conversion Definitions
Hz
Hz, or hertz, measures the number of cycles or vibrations per second, indicating how frequently an event repeats in one second. It is used in physics and engineering to quantify oscillations, wave frequencies, or rotations, providing a standard unit for periodic phenomena.
RPM
RPM, revolutions per minute, quantifies how many complete turns or rotations an object makes within one minute. It is a common measurement for motors, engines, and rotating machinery, reflecting rotational speed in a time-based context.
Conversion FAQs
How does increasing Hz affect rpm?
Increasing the Hz value directly increases rpm because the relationship rpm = Hz * 60 means that more cycles per second result in more rotations per minute, making the object spin faster.
Can I convert rpm to Hz using the same formula?
Yes, but in reverse. To convert rpm to Hz, divide the rpm value by 60: Hz = rpm / 60. This converts the rotations per minute back into cycles per second.
What equipment or scenarios use Hz and rpm?
Electric motors, turbines, oscilloscopes, and mechanical systems often use Hz to denote electrical frequency or oscillation rate, while rpm is used for engines, fans, and rotating machinery to measure their speed.
Is there a difference between rotational frequency and oscillation frequency?
Yes, rotational frequency (rpm or Hz) refers to how many times an object spins or completes a rotation per unit time. Oscillation frequency describes back-and-forth vibrations. Both are measured in Hz, but context differs.
Why is 60 used in the conversion formula?
The factor 60 arises because there are 60 seconds in a minute, and Hz measures cycles per second. To convert to rotations per minute, multiply by 60, scaling the frequency into a per-minute measurement.
