About Converting Petahertz to Attohertz
Petahertz and Attohertz 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: Petahertz is 1000000000000000 hertz units, and attohertz is 1e-18 hertz units.
Formula
attohertz = petahertz × 1e+33
This factor comes from each unit's defined relationship to the category's base unit: 1 petahertz equals 1e+15 base units, and 1 attohertz equals 1e-18 base units, so dividing one by the other gives the direct petahertz-to-attohertz factor of 1e+33.
Simple example
1 PHz × 1e+33 = 1e+33 aHz
1 petahertz = 1e+33 attohertz.
Real-world example
1,000 PHz × 1e+33 = 1e+36 aHz
1,000 petahertz = 1e+36 attohertz.

Frequently asked questions
How many attohertz are in 1 petahertz?
1 petahertz equals 1e+33 attohertz, using the exact defined conversion factor rather than an estimate.
How do I convert petahertz to attohertz?
Multiply the petahertz value by 1e+33. The converter above does this instantly to whatever precision you set.
How do I convert attohertz back to petahertz?
Use the reverse factor: 1 attohertz equals 1e-33 petahertz. You can also use the swap control in the converter above to flip the direction instantly.
What is a petahertz?
Petahertz (PHz) is a unit of frequency.
What is a attohertz?
Attohertz (aHz) is a unit of frequency.
Is the petahertz to attohertz conversion exact?
Yes. Both petahertz and attohertz are defined by fixed standards rather than physical artifacts, so the factor of 1e+33 used above is exact to as many digits as you choose to display.
