About Converting Attohertz to Petahertz
Attohertz and Petahertz 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: Attohertz is 1e-18 hertz units, and petahertz is 1000000000000000 hertz units.
Formula
petahertz = attohertz × 1e-33
This factor comes from each unit's defined relationship to the category's base unit: 1 attohertz equals 1e-18 base units, and 1 petahertz equals 1e+15 base units, so dividing one by the other gives the direct attohertz-to-petahertz factor of 1e-33.
Simple example
1 aHz × 1e-33 = 1e-33 PHz
1 attohertz = 1e-33 petahertz.
Real-world example
1,000 aHz × 1e-33 = 1e-30 PHz
1,000 attohertz = 1e-30 petahertz.

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