Frequency Calculator

Convert frequency between hertz, kilohertz, megahertz, and gigahertz. These units appear in audio, radio communication, electronics, vibration, processor clocks, and wave problems. The form asks for a Value, a From unit, and a To unit, then also lists the equivalent value in every supported unit.

How to use this calculator

Type the frequency value, choose the unit you are starting with, and choose the target unit. The converter uses hertz as the base unit: kHz = 1,000 Hz, MHz = 1,000,000 Hz, and GHz = 1,000,000,000 Hz. For signal power or sound level work, see the decibel calculator or sound level converter.

Conversion formula

Convert the input to hertz first, then divide by the target unit factor.

$target\ value = value \times from\ factor \div to\ factor$

For example, to convert 2.4 GHz to MHz:

$2.4 \times 1{,}000{,}000{,}000 \div 1{,}000{,}000 = 2{,}400$

So 2.4 GHz equals 2,400 MHz.

Common frequency conversions

Frequency is cycles per second. If you are comparing electrical quantities alongside frequency, the electric current converter and power converter may also be useful.
