Gigahertz to Kilohertz Conversion

Enter a frequency in gigahertz and read it back in kilohertz. One gigahertz is 1000000 kilohertz, so the kilohertz figure is always one million times the gigahertz figure.

Using the gigahertz to kilohertz calculator

Type the frequency in gigahertz into the input field and press Convert. The equivalent frequency in kilohertz appears below the buttons, ready to be copied with a single press of the Copy button.

Clear wipes the input and the result so you can run through another figure straight away.

How gigahertz and kilohertz relate

Both units measure frequency and differ only by scale. A gigahertz is one million kilohertz, while a kilohertz is 0.000001 gigahertz.

Because of that fixed gap, a positive value given in gigahertz turns into a much larger number when it is expressed in kilohertz, while zero stays at zero and a negative value keeps its sign.

GHz to kHz formula

The frequency f in kilohertz (kHz) equals the frequency f in gigahertz (GHz) multiplied by 1000000:

f(kHz) = f(GHz) × 1000000

For example, 3 gigahertz becomes 3 × 1000000 = 3000000 kilohertz.
