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.
PicohertzpHz
Target UnitThe picohertz (pHz) is a derived unit of frequency in the International System of Units (SI), representing one trillionth (10^-12) of a hertz (Hz). A hertz is defined as one cycle per second, thus a picohertz signifies an incredibly minuscule frequency of one cycle in one trillion seconds. This unit is essential in fields dealing with extremely low-frequency signals, such as certain branches of physics and engineering. The picohertz is often used in contexts where phenomena occur at exceptionally slow rates, enabling scientists and engineers to quantify and analyze these minute oscillations or cycles effectively. Its applications extend across various disciplines, providing a comprehensive framework for understanding low-frequency processes.
Current Use
In contemporary science and engineering, the picohertz is primarily utilized in fields such as geophysics, astrophysics, and quantum mechanics, where researchers analyze phenomena that occur at extremely low frequencies. For example, in geophysical studies, picohertz measurements can assist in the examination of seismic signals generated by tectonic movements, allowing for a better understanding of earthquake dynamics. Additionally, in the realm of quantum mechanics, the picohertz can be relevant when studying the behavior of particles at low energy states, where oscillations may occur over vast time scales. Countries leading in research employing picohertz include the United States, Germany, and Japan, where advanced laboratories and research institutions focus on low-frequency phenomena. Furthermore, the picohertz is increasingly being integrated into technological applications, such as in the development of sensitive sensors and detectors that operate at these low frequencies, driving innovation in various scientific and engineering domains.
Fun Fact
The picohertz is so small that it takes over 31,000 years for one cycle to complete.

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.
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.

History & Origin
The concept of measuring frequency has evolved alongside advancements in physics and technology. The term 'hertz' was named after Heinrich Hertz, a German physicist who made significant contributions to the study of electromagnetic waves in the late 19th century. The picohertz, as a subunit of hertz, was introduced to represent exceedingly low frequencies that are not easily quantified using larger units. While the hertz was officially adopted as the SI unit of frequency in 1960, the introduction of the picohertz came later as the need for measuring very low-frequency phenomena became apparent in various scientific fields. The increasing precision of measurement tools has further necessitated the use of such subunits, allowing for more detailed analysis of slow oscillatory processes.
Etymology: The term 'picohertz' derives from the prefix 'pico-', which denotes a factor of 10^-12, combined with 'hertz', the unit of frequency.
