Frequency Converter
1 MHz = 0.001 GHz
About the frequency category
How often something repeats: sound pitch, radio bands, CPU clocks, and mains power.
You will reach for these conversions when audio work: musical pitch and equipment specs (Hz, kHz), or radio: broadcast bands in kHz/MHz.
- Concert pitch A above middle C: 440 Hz
- European mains power: 50 Hz, US: 60 Hz
Popular frequency conversions
Common mistakes
- kHz vs MHz in radio: a factor of 1,000; FM is around 100 MHz, AM around 1 MHz
- Mains frequency does not affect voltage, which is why 50/60 Hz devices are often but not always interchangeable
