How to Convert Hertz to Gigahertz
To convert hertz to gigahertz, multiply the frequency by the following conversion ratio: 1e-9 gigahertz/hertz.
Since one hertz is equal to 1e-9 gigahertz, you can use this simple formula to convert:
The frequency in gigahertz is equal to the frequency in hertz multiplied by 1e-9.
For example, here's how to convert 5 hertz to gigahertz using the formula above.
How Many Gigahertz Are in a Hertz?
There are 1e-9 gigahertz in a hertz, which is why we use this value in the formula above.
Our hertz to gigahertz calculator automatically converts your frequency measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Hertz and gigahertz are both units used to measure frequency. Keep reading to learn more about each unit.
What Is a Hertz?
SI unit of frequency equal to 1 cycle per second. It serves as a primary reference unit for measuring frequency across scientific and practical applications. [1]
The hertz is classified as an International System of Units (SI) unit of frequency. Hertz can be abbreviated as Hz; for example, 1 hertz can be written as 1 Hz.
As the primary coherent reference unit for frequency in this category, all other frequency units are mathematically anchored to the hertz (Hz).
In practice, hertz (Hz) are widely used across standard frequency applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
What Is a Gigahertz?
A gigahertz is a unit of frequency equal to 1,000,000,000 hertz (Hz), the base unit for frequency. Equal to 1,000,000,000 Hz. [2]
The gigahertz is classified as a metric and SI-compatible unit of frequency. Gigahertz can be abbreviated as GHz; for example, 1 gigahertz can be written as 1 GHz.
In the metric system, "giga" is the standard SI prefix for billions, or 10⁹. This makes the gigahertz (GHz) a convenient decimal multiple of the hertz (Hz).
In practice, gigahertz (GHz) are widely used across large-scale industrial, bulk, and macro-level frequency specifications within SI metric workflows, engineering documentation, and technical data sheets.
When converting frequency between hertz (Hz) and gigahertz (GHz), keep full floating-point precision (1 Hz = 1e-9 GHz; 1 GHz = 1,000,000,000 Hz) during intermediate calculations and round only the final gigahertz figure to match your instrument tolerance.
