How to Convert Gigahertz to Hertz

To convert a measurement in gigahertz to a measurement in hertz, multiply the frequency by the following conversion ratio: 1,000,000,000 hertz/gigahertz.

Since one gigahertz is equal to 1,000,000,000 hertz, you can use this simple formula to convert:

hertz = gigahertz × 1,000,000,000

The frequency in hertz is equal to the frequency in gigahertz multiplied by 1,000,000,000.

For example, here's how to convert 5 gigahertz to hertz using the formula above.
hertz = (5 GHz × 1,000,000,000) = 5,000,000,000 Hz

How Many Hertz Are in a Gigahertz?

There are 1,000,000,000 hertz in a gigahertz, which is why we use this value in the formula above.

1 GHz = 1,000,000,000 Hz

Gigahertz and hertz are both units used to measure frequency. Keep reading to learn more about each unit of measure.

What Is a Gigahertz?

Gigahertz is a measure of frequency equal to one billion cycles per second.

The gigahertz is a multiple of the hertz, which is the SI derived unit for frequency. In the metric system, "giga" is the prefix for billions, or 109. Gigahertz can be abbreviated as GHz; for example, 1 gigahertz can be written as 1 GHz.

What Is a Hertz?

One hertz is formally defined as the frequency of one cycle per second.[1]

The hertz is the SI derived unit for frequency in the metric system. Hertz can be abbreviated as Hz; for example, 1 hertz can be written as 1 Hz.

Frequency in hertz can be expressed using the formula:

Hz = Cycles / Time in Seconds
