What does femtohertz measure?

Femtohertz measures cycles per second at a frequency of 10^-15 hertz, representing oscillations occurring over millions of years.

When should I convert femtohertz to nanohertz?

Conversion is helpful when translating ultra-low frequency signals to a higher frequency scale applicable to multi-year or multi-decade phenomena.

Are there challenges in converting femtohertz to nanohertz?

Yes, the difference in scale results in very small numbers which may challenge measurement precision or data interpretation.
