About Converting Terahertz to Attohertz
Terahertz 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: Terahertz is 1000000000000 hertz units, and attohertz is 1e-18 hertz units.
Formula
attohertz = terahertz × 1e+30
This factor comes from each unit's defined relationship to the category's base unit: 1 terahertz equals 1e+12 base units, and 1 attohertz equals 1e-18 base units, so dividing one by the other gives the direct terahertz-to-attohertz factor of 1e+30.
Simple example
1 THz × 1e+30 = 1e+30 aHz
1 terahertz = 1e+30 attohertz.
Real-world example
1,000 THz × 1e+30 = 1e+33 aHz
1,000 terahertz = 1e+33 attohertz.

Reverse conversion: Attohertz to Terahertz
1e+30 aHz × 1e-30 = 1 THz
1e+30 attohertz = 1 terahertz.
terahertz = attohertz × 1e-30

Frequently asked questions
How many attohertz are in 1 terahertz?
1 terahertz equals 1e+30 attohertz, using the exact defined conversion factor rather than an estimate.
How do I convert terahertz to attohertz?
Multiply the terahertz value by 1e+30. The converter above does this instantly to whatever precision you set.
How do I convert attohertz back to terahertz?
Use the reverse factor: 1 attohertz equals 1e-30 terahertz. You can also use the swap control in the converter above to flip the direction instantly.
What is a terahertz?
Terahertz (THz) is a unit of frequency.
What is a attohertz?
Attohertz (aHz) is a unit of frequency.
Is the terahertz to attohertz conversion exact?
Yes. Both terahertz and attohertz are defined by fixed standards rather than physical artifacts, so the factor of 1e+30 used above is exact to as many digits as you choose to display.
