What is an attohertz?

An attohertz is an SI-derived frequency unit equal to 10⁻¹⁸ hertz, used to measure extremely slow oscillations occurring over timescales of about 10¹⁸ seconds.

When should I convert attohertz to picohertz?

You convert attohertz to picohertz to represent ultra-low frequencies on more manageable timescales, such as comparing cosmological oscillations to geophysical periodicities lasting thousands to millions of years.

Are attohertz and picohertz commonly measured?

Due to their extremely low frequencies, these units are mostly theoretical and used in models rather than practical measurement.
