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.
DecihertzdHz
Target UnitDecihertz (dHz) is a derived unit of frequency in the International System of Units (SI) that represents one-tenth of a hertz (Hz), with 1 dHz equating to 0.1 Hz. Frequency, defined as the number of occurrences of a repeating event per unit time, measures how often an event occurs in a given time period. In terms of time, one hertz signifies one cycle per second. A decihertz, therefore, indicates that an event occurs once every ten seconds. This unit is particularly useful in contexts where lower frequencies are involved, allowing for more precise readings in certain applications. Decihertz is commonly used in scientific and engineering fields to quantify frequencies that occur at a slower rate than typical hertz measures.
Current Use
Decihertz is utilized in various industries where low-frequency measurements are relevant, such as acoustics, seismology, and telecommunications. In audio engineering, decihertz can help describe very low-frequency sound waves, such as those produced by large speakers or natural phenomena. In the field of seismology, where earthquake vibrations are measured, decihertz can be used to quantify the frequency of seismic waves that occur over extended periods. Telecommunications engineers may also use decihertz when dealing with low-frequency signals, particularly in the context of modulation techniques. Countries around the world, particularly those adhering to the SI units, utilize decihertz in scientific research and industry applications, ensuring consistency in measurements. Its application ranges from academic research in physics to practical engineering solutions across various technological domains.
Fun Fact
The hertz, from which decihertz is derived, was named after Heinrich Hertz, who was the first to conclusively prove the existence of electromagnetic waves.

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.
