About Converting Picohertz to Attohertz
Picohertz and Attohertz are both scientific-measurement units, spanning everything from atomic and laboratory scales to astronomical distances — the kind of conversion that comes up constantly in physics, chemistry, and astronomy when a result needs to move between conventions used in different subfields. Specifically: Picohertz is 1e-12 hertz units, and attohertz is 1e-18 hertz units.
Formula
attohertz = picohertz × 1000000
This factor comes from each unit's defined relationship to the category's base unit: 1 picohertz equals 1e-12 base units, and 1 attohertz equals 1e-18 base units, so dividing one by the other gives the direct picohertz-to-attohertz factor of 1000000.
Simple example
1 pHz × 1000000 = 1,000,000 aHz
1 picohertz = 1,000,000 attohertz.
Real-world example
10 pHz × 1000000 = 10,000,000 aHz
10 picohertz = 10,000,000 attohertz.

Frequently asked questions
How many attohertz are in 1 picohertz?
1 picohertz equals 1,000,000 attohertz, using the exact defined conversion factor rather than an estimate.
How do I convert picohertz to attohertz?
Multiply the picohertz value by 1000000. The converter above does this instantly to whatever precision you set.
How do I convert attohertz back to picohertz?
Use the reverse factor: 1 attohertz equals 0.000001 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 scientific units.
What is a attohertz?
Attohertz (aHz) is a unit of scientific units.
Is the picohertz to attohertz conversion exact?
Yes. Both picohertz and attohertz are defined by fixed standards rather than physical artifacts, so the factor of 1000000 used above is exact to as many digits as you choose to display.
Why does this category span everything from atomic to astronomical scales?
Scientific work spans an enormous range of physical scales, from atomic distances (measured in angstroms or atomic mass units) to interstellar distances (measured in astronomical units or parsecs), so this category groups SI-derived and scale-specific units that researchers commonly need to convert between within their field.
