About Converting Picohertz to Gigahertz
Picohertz and Gigahertz 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: Picohertz is 1e-12 hertz units, and gigahertz is 1000000000 hertz units.
Formula
gigahertz = picohertz × 1e-21
This factor comes from each unit's defined relationship to the category's base unit: 1 picohertz equals 1e-12 base units, and 1 gigahertz equals 1000000000 base units, so dividing one by the other gives the direct picohertz-to-gigahertz factor of 1e-21.
Simple example
1 pHz × 1e-21 = 1e-21 GHz
1 picohertz = 1e-21 gigahertz.
Real-world example
1,000 pHz × 1e-21 = 1e-18 GHz
1,000 picohertz = 1e-18 gigahertz.

Reverse conversion: Gigahertz to Picohertz
1e-21 GHz × 1e+21 = 1 pHz
1e-21 gigahertz = 1 picohertz.
picohertz = gigahertz × 1e+21

Frequently asked questions
How many gigahertz are in 1 picohertz?
1 picohertz equals 1e-21 gigahertz, using the exact defined conversion factor rather than an estimate.
How do I convert picohertz to gigahertz?
Multiply the picohertz value by 1e-21. The converter above does this instantly to whatever precision you set.
How do I convert gigahertz back to picohertz?
Use the reverse factor: 1 gigahertz equals 1e+21 picohertz. You can also use the swap control in the converter above to flip the direction instantly.
What is a picohertz?
Picohertz (pHz) is a unit of frequency.
What is a gigahertz?
Gigahertz (GHz) is a unit of frequency.
Is the picohertz to gigahertz conversion exact?
Yes. Both picohertz and gigahertz are defined by fixed standards rather than physical artifacts, so the factor of 1e-21 used above is exact to as many digits as you choose to display.
