Microhertz (µHz)
The microhertz (symbol: µHz) is an SI unit of frequency equivalent to one millionth of a hertz (10^-6 Hz), representing one cycle approximately every 11.57 days. It is used in fields that study extremely slow oscillations, such as helioseismology, asteroseismology, and oceanography. Scientists use microhertz measurements to analyze internal acoustic oscillations of stars and long-period gravitational and tidal waves in Earth's oceans.
