Unit Explanations
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.
MicrohertzµHz
Target UnitThe microhertz (µHz) is a unit of frequency in the International System of Units (SI) representing one millionth (10^-6) of a hertz (Hz). A hertz is defined as one cycle per second, so a microhertz corresponds to one cycle in one million seconds, or approximately 11.57 days. This unit is particularly useful in various scientific fields, including geophysics and biophysics, where phenomena occur at very low frequencies, such as seismic waves or biological rhythms. The µHz is also employed in the context of oscillatory systems wherein precision at extremely low frequency levels is critical, enabling researchers and engineers to analyze systems that operate at such minute frequencies effectively.
Current Use
Microhertz is widely used in various scientific and engineering fields to measure extremely low frequencies. In geophysics, researchers may employ microhertz to analyze seismic waves generated by tectonic activity or other geological processes. In the biomedical sector, microhertz measurements can be critical for studying biological rhythms and processes that operate on a long timescale, such as circadian rhythms. Technologies such as brainwave monitoring and heart rate variability assessment often use microhertz for more precise data collection. Additionally, in the field of telecommunications, microhertz can assist in studying the effects of extremely low-frequency signals on communication systems. Countries with advanced research facilities, such as the United States, Germany, and Japan, regularly utilize microhertz across industries ranging from environmental science to medical diagnostics.
Fun Fact
Microhertz frequencies correspond to phenomena occurring over days and weeks, making them fascinating for long-term studies.

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.
