Convert GHz to Hz

One gigahertz is one billion hertz, so moving from GHz to Hz takes a single multiplication by 1000000000. Type a frequency, press Convert, and the hertz value appears right below.

How to convert gigahertz to hertz

Gigahertz and hertz measure the same thing — frequency — and they sit a fixed distance apart: 1 GHz = 1000000000 Hz. Because that gap never changes, any gigahertz figure becomes a hertz figure through one multiplication.

Type the number of gigahertz into the field, press Convert, and read the matching hertz value. Copy takes the answer with you, and Clear empties the field so you can try another frequency.

GHz to hertz formula

f (Hz) = f (GHz) × 1000000000

Put into words: the frequency in hertz equals the frequency in gigahertz multiplied by one billion. Going the other way, 1 Hz = 0.000000001 GHz, so a hertz figure is turned back into gigahertz by dividing by 1000000000.

Worked example

Take 3 gigahertz: 3 × 1000000000 = 3000000000 Hz. The same arithmetic gives 0.001 GHz = 1000000 Hz and 0.1 GHz = 100000000 Hz, matching the rows listed in the table.
