Result: 6000 rpm
Converting 100 hz to rpm gives 6000 rpm. This means that a frequency of 100 cycles per second corresponds to 6000 revolutions per minute. The conversion helps in understanding how fast a rotating object spins based on its frequency.
To convert from hertz (hz), which measures cycles per second, to revolutions per minute (rpm), multiply the frequency by 60. Since 1 hz equals 1 cycle per second, and there are 60 seconds in a minute, the formula is rpm = hz × 60. So, 100 hz × 60 equals 6000 rpm, showing the rotation speed.

Conversion Formula
The conversion from hz to rpm is based on the fact that 1 hertz equals 1 cycle per second. To find rpm, you multiply the hz value by 60, because there are 60 seconds in a minute. This calculation turns a measure of frequency into a measure of rotational speed.
For example, if you have 50 hz: 50 × 60 = 3000 rpm. This process works because each cycle per second translates to a full rotation per second, and multiplying by 60 scales that to rotations per minute. So, the formula is rpm = hz × 60.
Conversion Example
- Convert 75 hz to rpm:
- Multiply 75 by 60.
- 75 × 60 = 4500 rpm.
- Convert 25 hz to rpm:
- Multiply 25 by 60.
- 25 × 60 = 1500 rpm.
- Convert 120 hz to rpm:
- Multiply 120 by 60.
- 120 × 60 = 7200 rpm.
- Convert 10 hz to rpm:
- Multiply 10 by 60.
- 10 × 60 = 600 rpm.

Conversion Definitions
hz
Hertz (hz) measures the number of cycles or oscillations that occur in one second, indicating frequency. It is used to quantify how many times a repeating event happens per second, often in electronic signals, sound waves, and rotational systems.
rpm
Revolutions per minute (rpm) indicates how many complete turns or rotations a rotating object makes in one minute. It is a common measurement for motor speeds, turbines, and spinning machinery, providing a clear sense of rotational velocity.
Conversion FAQs
How accurate is the conversion from hz to rpm?
The conversion is highly accurate when using the formula rpm = hz × 60. This calculation assumes that each cycle in hz corresponds to one complete rotation, which holds true in most mechanical and electrical contexts where the cycle equals one revolution.
What happens if the frequency is not an exact multiple of 60?
If the frequency is a non-integer or not a multiple of 60, the rpm value will be fractional, reflecting the precise speed. For example, 33.3 hz equals 1998 rpm, accurately representing the rotation speed even if it doesn’t divide evenly.
Can this conversion be used for all types of rotating equipment?
Yes, as long as each cycle corresponds to one rotation, the formula applies. For systems where cycles and rotations are linked differently, adjustments may be necessary, but generally, the simple multiplication by 60 works well for standard rotational measurements.
Does the conversion change if the system uses different units?
Conversion remains consistent because the formula directly relates frequency in hz to rpm through the multiplication by 60. Changing units would require converting to standard units before applying the formula.
