About Converting Attohertz to Nanohertz
Attohertz 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: Attohertz is 1e-18 hertz units, and nanohertz is 1e-9 hertz units.
Formula
nanohertz = attohertz × 1e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 attohertz equals 1e-18 base units, and 1 nanohertz equals 1e-9 base units, so dividing one by the other gives the direct attohertz-to-nanohertz factor of 1e-9.
Simple example
1 aHz × 1e-9 = 1e-9 nHz
1 attohertz = 1e-9 nanohertz.
Real-world example
1,000 aHz × 1e-9 = 0.000001 nHz
1,000 attohertz = 0.000001 nanohertz.

Reverse conversion: Nanohertz to Attohertz
1e-9 nHz × 1000000000 = 1 aHz
1e-9 nanohertz = 1 attohertz.
attohertz = nanohertz × 1000000000

Frequently asked questions
How many nanohertz are in 1 attohertz?
1 attohertz equals 1e-9 nanohertz, using the exact defined conversion factor rather than an estimate.
How do I convert attohertz to nanohertz?
Multiply the attohertz value by 1e-9. The converter above does this instantly to whatever precision you set.
How do I convert nanohertz back to attohertz?
Use the reverse factor: 1 nanohertz equals 1,000,000,000 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 nanohertz?
Nanohertz (nHz) is a unit of frequency.
Is the attohertz to nanohertz conversion exact?
Yes. Both attohertz and nanohertz are defined by fixed standards rather than physical artifacts, so the factor of 1e-9 used above is exact to as many digits as you choose to display.
