About Converting Gigahertz to Exahertz
Gigahertz and Exahertz both describe how fast something cycles or rotates, and the conversion is a routine part of reading a car tachometer or motor spec sheet against a scientific frequency figure. Specifically: Gigahertz is 1000000000 hertz units, and exahertz is 1000000000000000000 hertz units.
Formula
exahertz = gigahertz × 1e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 gigahertz equals 1000000000 base units, and 1 exahertz equals 1e+18 base units, so dividing one by the other gives the direct gigahertz-to-exahertz factor of 1e-9.
Simple example
1 GHz × 1e-9 = 1e-9 EHz
1 gigahertz = 1e-9 exahertz.
Real-world example
1,000 GHz × 1e-9 = 0.000001 EHz
1,000 gigahertz = 0.000001 exahertz.

Reverse conversion: Exahertz to Gigahertz
1e-9 EHz × 1000000000 = 1 GHz
1e-9 exahertz = 1 gigahertz.
gigahertz = exahertz × 1000000000

Frequently asked questions
How many exahertz are in 1 gigahertz?
1 gigahertz equals 1e-9 exahertz, using the exact defined conversion factor rather than an estimate.
How do I convert gigahertz to exahertz?
Multiply the gigahertz value by 1e-9. The converter above does this instantly to whatever precision you set.
How do I convert exahertz back to gigahertz?
Use the reverse factor: 1 exahertz equals 1,000,000,000 gigahertz. You can also use the swap control in the converter above to flip the direction instantly.
What is a gigahertz?
Gigahertz (GHz) is a unit of frequency.
What is a exahertz?
Exahertz (EHz) is a unit of frequency.
Is the gigahertz to exahertz conversion exact?
Yes. Both gigahertz and exahertz are defined by fixed standards rather than physical artifacts, so the factor of 1e-9 used above is exact to as many digits as you choose to display.
