How many hertz are in one gigahertz?

One gigahertz equals 1,000,000,000 Hz. The formula is Hz = GHz × 1,000,000,000.

How do I convert gigahertz to hertz?

Multiply the value in gigahertz by 1,000,000,000. For example, 100 × 1,000,000,000 = 100,000,000,000 — so 100 GHz = 100,000,000,000 Hz.

What is a hertz? From radio waves to screen refresh rates

A single unit — "once per second" — ties together nearly all of modern technology. The same hertz describes the note you hear, the power in your outlet, the reach of a radio signal, how smooth your phone screen feels, and your processor's clock. Here is how a count of repetitions per second became the common denominator of the digital world.
