femtohertz to attohertz
Convert femtohertz (fHz) to attohertz (aHz). Use an editable frequency converter, conversion formula, and reference table.
1 fHz = 1,000 aHz
Conversion formula
One femtohertz equals 1,000 attohertz. Multiply your value in femtohertz by this factor to get attohertz. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 femtohertz:5 × 1,000 = 5,000 aHz

About these measurements
Frequency measures cycles per second.
The base reference used here is the hertz. One femtohertz is 1e-15 base units; one attohertz is 1e-18 base units.
Important distinctions
Frequency is the reciprocal of period, not angular velocity.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert fHz to aHz?
Multiply the quantity in fHz by 1,000. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the attohertz to femtohertz converter.
