Hertz
Hz
Definition
The Hertz is the SI base unit of frequency, representing one cycle per second. It is named after Heinrich Hertz, a German physicist who made important contributions to the study of electromagnetic waves. The hertz is used to measure the frequency of periodic phenomena in physics, electronics, and telecommunications.
History/Origin
The hertz was adopted as the SI unit of frequency in 1960, replacing the older unit "cycles per second." It was named after Heinrich Hertz (1857-1894), who was the first to conclusively prove the existence of electromagnetic waves. Hertz's experiments in the 1880s demonstrated that electromagnetic waves could be generated and detected, laying the foundation for radio technology.
Current Use
Widely used in electronics, telecommunications, radio broadcasting, computer processors, and scientific research. It measures the frequency of alternating current, radio waves, sound waves, and other periodic phenomena. Essential for understanding resonance, harmonics, and wave behavior in various physical systems.

Millihertz
mHz
Definition
The Millihertz is a unit of frequency equal to 10^-3 hertz, representing frequencies in the extremely low sub-audio range. It corresponds to wavelengths in the hundreds of millions of kilometers range and is used in scientific instruments, low-frequency oscillators, and specialized measurement applications.
History/Origin
The millihertz unit was established as part of the SI system to provide intermediate frequency measurements between the base hertz and smaller frequency units. It represents frequencies that are 3 orders of magnitude lower than the base hertz unit, corresponding to wavelengths in the extremely long-wave radio region.
Current Use
Used in scientific instruments, low-frequency oscillators, and specialized measurement applications. It is particularly useful for measuring frequencies in the extremely low sub-audio range and for understanding the behavior of systems that operate at extremely low frequencies.
