How to Convert Gigahertz to Exahertz

To convert gigahertz to exahertz, multiply the frequency by the following conversion ratio: 1e-9 exahertz/gigahertz.

Since one gigahertz is equal to 1e-9 exahertz, you can use this simple formula to convert:

exahertz = gigahertz × 1e-9

The frequency in exahertz is equal to the frequency in gigahertz multiplied by 1e-9.

For example, here's how to convert 5 gigahertz to exahertz using the formula above.

exahertz = (5 GHz × 1e-9) = 5e-9 EHz

How Many Exahertz Are in a Gigahertz?

There are 1e-9 exahertz in a gigahertz, which is why we use this value in the formula above.

1 GHz = 1e-9 EHz|1 EHz = 1,000,000,000 GHz

Our gigahertz to exahertz calculator automatically converts your frequency measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

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

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. [1]

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.

What Is an Exahertz?

An exahertz is a unit of frequency equal to 1e+18 hertz (Hz), the base unit for frequency. Equal to 10¹⁸ Hz. [2]

The exahertz is classified as an International System of Units (SI) unit of frequency. Exahertz can be abbreviated as EHz; for example, 1 exahertz can be written as 1 EHz.

In the metric system, "exa" is the standard SI prefix for quintillions, or 10¹⁸. This makes the exahertz (EHz) a convenient decimal multiple of the hertz (Hz).

In practice, exahertz (EHz) are widely used across large-scale industrial, bulk, and macro-level frequency specifications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.

When converting frequency between gigahertz (GHz) and exahertz (EHz), keep full floating-point precision (1 GHz = 1e-9 EHz; 1 EHz = 1,000,000,000 GHz) during intermediate calculations and round only the final exahertz figure to match your instrument tolerance.
