About Converting Gigahertz to Nanohertz
Gigahertz and Nanohertz 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 nanohertz is 1e-9 hertz units.
Formula
nanohertz = gigahertz × 1e+18
This factor comes from each unit's defined relationship to the category's base unit: 1 gigahertz equals 1000000000 base units, and 1 nanohertz equals 1e-9 base units, so dividing one by the other gives the direct gigahertz-to-nanohertz factor of 1e+18.
Simple example
1 GHz × 1e+18 = 1e+18 nHz
1 gigahertz = 1e+18 nanohertz.
Real-world example
1,000 GHz × 1e+18 = 1e+21 nHz
1,000 gigahertz = 1e+21 nanohertz.

Reverse conversion: Nanohertz to Gigahertz
1e+18 nHz × 1e-18 = 1 GHz
1e+18 nanohertz = 1 gigahertz.
gigahertz = nanohertz × 1e-18

Frequently asked questions
How many nanohertz are in 1 gigahertz?
1 gigahertz equals 1e+18 nanohertz, using the exact defined conversion factor rather than an estimate.
How do I convert gigahertz to nanohertz?
Multiply the gigahertz value by 1e+18. The converter above does this instantly to whatever precision you set.
How do I convert nanohertz back to gigahertz?
Use the reverse factor: 1 nanohertz equals 1e-18 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 nanohertz?
Nanohertz (nHz) is a unit of frequency.
Is the gigahertz to nanohertz conversion exact?
Yes. Both gigahertz and nanohertz are defined by fixed standards rather than physical artifacts, so the factor of 1e+18 used above is exact to as many digits as you choose to display.
