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.
TerahertzTHz
Target UnitThe terahertz (THz) is a unit of frequency in the International System of Units (SI) that represents one trillion hertz, or 10^12 hertz. It is commonly used in various fields of science and engineering to quantify electromagnetic waves, particularly in the infrared and microwave regions of the electromagnetic spectrum. The terahertz frequency range is significant for applications in spectroscopy, telecommunications, and imaging technologies. Frequencies in the terahertz range can penetrate materials, enabling non-destructive testing and imaging. As such, the terahertz unit plays a crucial role in advancing research and technology across multiple disciplines.
Current Use

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.
