HertzHz
Source UnitThe hertz (Hz) is the standard unit of frequency in the International System of Units (SI), representing the number of cycles of a periodic phenomenon occurring in one second. It is defined as one cycle per second and is utilized to quantify oscillations, waves, and repetitive events in various fields, including physics, engineering, and telecommunications. The hertz encompasses a wide range of frequencies, from extremely low frequencies in the audible spectrum to extremely high frequencies in radio and microwave domains. The unit is named after Heinrich Hertz, a German physicist who made significant contributions to the study of electromagnetic waves. His pioneering experiments in the late 19th century led to the foundational understanding of wireless communication, making the hertz a pivotal unit in both theoretical and applied physics.
Current Use
The hertz is widely utilized across various industries, including telecommunications, audio engineering, and medical equipment. In telecommunications, frequencies are crucial for the transmission of data and signals, with radio frequencies ranging from 3 kHz to 300 GHz being used for broadcasting and wireless communication. In audio engineering, sound frequencies are measured in hertz, with the human auditory range typically between 20 Hz and 20 kHz, impacting music production and sound design. Additionally, in medical imaging, techniques such as MRI utilize radio frequency signals measured in hertz to create detailed images of the body. Countries around the world, including the United States, Germany, and Japan, employ the hertz in various applications, ensuring uniformity in frequency measurements essential for technology and scientific research.
Fun Fact
The hertz is named after Heinrich Hertz, who was the first to conclusively prove the existence of electromagnetic waves.
NanohertznHz
Target UnitA nanohertz (nHz) is a unit of frequency that is equal to one billionth of a hertz (1 nHz = 10^-9 Hz). This unit is used to measure very low-frequency phenomena, particularly in the contexts of geophysics, astrophysics, and certain areas of engineering. The hertz (Hz) itself is defined as one cycle per second, thereby making the nanohertz an extremely diminutive measure. Frequencies in this range are often encountered in the study of seismic waves, gravitational waves, and various biological processes that exhibit oscillatory behavior on very long timescales. In practical terms, the nanohertz scale is relevant when analyzing signals that occur over extended periods, often requiring sophisticated detection techniques to observe such minute variations.
Current Use
Nanohertz is primarily used in specialized scientific fields, including astrophysics, geophysics, and biomedical research. In astrophysics, it is instrumental in observing gravitational waves, which oscillate at frequencies often measured in the nanohertz range. The Laser Interferometer Gravitational-Wave Observatory (LIGO) employs nanohertz measurements to detect subtle spacetime distortions caused by massive astrophysical events. In geophysics, nanohertz frequencies are critical for studying tectonic movements and seismic activity, where low-frequency vibrations can indicate impending geological events. Additionally, in biomedical applications, researchers examine brain waves and other physiological oscillations that may occur at nanohertz frequencies, contributing to our understanding of various biological processes. Countries leading in nanohertz research include the United States, Germany, and Japan, where advanced laboratories and observatories facilitate cutting-edge studies.
Fun Fact
The lowest frequency ever detected in gravitational waves was around 1 nHz.

History & Origin
The concept of frequency has been recognized since the early studies of harmonic motion and waves. The term 'hertz' was adopted in the late 19th century after the work of Heinrich Hertz, who first conclusively demonstrated the existence of electromagnetic waves in 1887. Hertz's experiments validated James Clerk Maxwell's electromagnetic theory, which predicted that light and radio waves travel as oscillating electric and magnetic fields. The significance of Hertz’s work led to the establishment of the hertz as a unit of measurement for frequency in the 1930s, formalized by the International Electrotechnical Commission (IEC) in 1930 and further recognized by the General Conference on Weights and Measures (CGPM) in 1960.
Etymology: The term 'hertz' is derived from the last name of Heinrich Hertz, which was adopted as a unit of measurement in honor of his contributions to electromagnetism.
