Quick Reference Formulas
- 1 Hz = 1 cycle per second
- 1 kHz = 1,000 Hz
- 1 MHz = 1,000,000 Hz
- 1 GHz = 1,000,000,000 Hz
- 1 THz = 1,000,000,000,000 Hz
- Angular Frequency (rad/s) = 2π × f(Hz)
- Period (s) = 1 / f(Hz)
- Beats Per Minute (BPM) = f(Hz) × 60
How to Use the Frequency Converter
Using the tool is simple and straightforward:
- Enter a frequency value (for example,
440or2.5e3). - Select the unit you want to convert from — options include Hz, kHz, MHz, GHz, THz, rad/s, seconds, and BPM.
- Click “Convert” to instantly view all corresponding results.
- You can also swap units or clear results with one click.
