What does picohertz measure?

Picohertz measures extremely low frequencies equal to one cycle per 10¹² seconds, representing oscillations on timescales of about 31,700 years.

Why convert picohertz to nanohertz?

Converting to nanohertz helps express ultra-low frequencies into a unit that corresponds to multi-year and multi-decade phenomena, making analysis more manageable.

Are there precision issues with this conversion?

Yes, because picohertz and nanohertz represent frequencies differing by three orders of magnitude, conversions may cause precision loss if applied outside suitable ranges.
