Frequency Converter
What this does
Converts frequency: hertz, kilohertz, megahertz, gigahertz, revolutions per minute and cycles per second, and shows the period (1/f).
Handy anchors
- Mains power is 50 or 60 Hz. Concert A is 440 Hz. Wi-Fi is 2.4 or 5 GHz.
- 3,000 rpm = 50 Hz.
Good to know
Period in milliseconds = 1000 / Hz. A 60 Hz screen refreshes every 16.7 ms.
