Hertz to Microhertz Converter

A hertz (Hz) is the SI base unit of frequency, defined as one cycle per second. It represents the fundamental measure of frequency, named after German physicist Heinrich Hertz, and forms the basis for all other frequency measurements.

The hertz was named after Heinrich Hertz in 1930, who proved the existence of electromagnetic waves. It was adopted as the SI unit of frequency in 1960, replacing the older term 'cycles per second' and providing a unified measure for all periodic phenomena.

Hertz is universally used for measuring all types of frequencies, from sound waves to electromagnetic radiation. It's fundamental in physics, engineering, music, and technology, serving as the base unit for all frequency measurements and calculations.

A microhertz (µHz) is a unit of frequency equal to one millionth of a hertz (10⁻⁶ Hz). It represents extremely low frequencies found in astronomical phenomena, very slow biological processes, and precision scientific measurements.

The microhertz became important with advanced astronomical observations and precision scientific measurements. It was particularly crucial for describing stellar oscillations, planetary motions, and other astronomical phenomena with very long periods.

Microhertz is used in astronomy for stellar seismology, precision timing systems, long-term biological studies, and advanced scientific research. It's essential for measuring astronomical oscillations, very slow biological rhythms, and ultra-precision frequency standards.
