Unit aHz
Name attohertz
Category Frequency
Details Attohertz (aHz) is a unit of frequency in the International System of Units (SI). It represents 10^(-18) hertz (Hz), meaning that one attohertz is equal to 0.000000000000000001 Hz. This is an extremely low frequency and is typically encountered in the fields of physics or engineering when dealing with very slow or long-period oscillatory phenomena. For example, it can be used to represent the frequency of slow atomic-level transitions or massive celestial events like the oscillations of supermassive black holes.
