Frequency Converter — Free Online Frequency Unit Conversion

Frequency conversion is vital in electronics, telecommunications, music, and physics. Convert between hertz, kilohertz, megahertz, gigahertz, and RPM with our precise frequency converter.

What is a Frequency Converter?

Frequency measures how many times an event repeats per unit of time. The SI unit is the hertz (Hz), meaning one cycle per second. Higher multiples (kHz, MHz, GHz, THz) are used extensively in electronics, radio, and computing.

Common Uses for Frequency Conversion

  • Electronics — Converting between Hz, kHz, and MHz for circuit design and signal processing
  • Telecommunications — Working with radio frequencies in MHz and GHz
  • Music — Understanding musical note frequencies in Hz
  • Computing — Converting processor clock speeds between GHz and MHz
  • Mechanical Engineering — Converting RPM to Hz for rotating machinery

Tips for Frequency Conversion

  • Middle C on a piano is 261.63 Hz
  • Wi-Fi operates at 2.4 GHz and 5 GHz — that's 2,400,000,000 and 5,000,000,000 cycles per second
  • 1 RPM = 1/60 Hz — divide RPM by 60 to get hertz
