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, 440 or 2.5e3).
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.
