- Select Units: Choose the Start unit (e.g., Hertz) and Target unit (e.g., RPM) from the dropdowns.
- Enter Value: Type the frequency value. The tool supports standard numbers and scientific notation.
- Instant Result: The converted value appears instantly. You'll also see the corresponding period and approximate wavelength.
- Visualize: Check the spectrum bar to see where your frequency falls on the EM/Audio spectrum.
- 1 Hz = 1 Cycle/Second = 60 RPM
- 1 kHz = 1,000 Hz
- 1 MHz = 1,000,000 Hz
- 1 GHz = 1,000,000,000 Hz
- 60 RPM = 1 Hz
- 100 BPM = 1.66 Hz
Understanding Frequency
Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as "temporal frequency". The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.
- Hertz (Hz): The SI unit of frequency, defined as one cycle per second.
- RPM (Revolutions Per Minute): A unit of rotational speed or the frequency of rotation around a fixed axis.
- BPM (Beats Per Minute): A unit typically used as a measure of tempo in music and heart rate.
