Hertz to Terahertz Converter

A hertz (Hz) is the SI base unit of frequency, defined as one cycle per second. It represents the fundamental measure of frequency, named after German physicist Heinrich Hertz, and forms the basis for all other frequency measurements.

The hertz was named after Heinrich Hertz in 1930, who proved the existence of electromagnetic waves. It was adopted as the SI unit of frequency in 1960, replacing the older term 'cycles per second' and providing a unified measure for all periodic phenomena.

Hertz is universally used for measuring all types of frequencies, from sound waves to electromagnetic radiation. It's fundamental in physics, engineering, music, and technology, serving as the base unit for all frequency measurements and calculations.

A terahertz (THz) is a unit of frequency equal to one trillion hertz (10¹² Hz). It represents extremely high frequencies typically found in infrared radiation, molecular vibrations, and advanced telecommunications research.

The terahertz became important with the development of advanced spectroscopy and telecommunications research in the late 20th century. It was particularly crucial for describing frequencies in the 'terahertz gap' between microwave and infrared radiation, opening new fields in materials science and medical imaging.

Terahertz frequencies are used in advanced spectroscopy, medical imaging, security scanning, materials research, and cutting-edge telecommunications. They're essential for terahertz imaging systems, molecular spectroscopy, and research into next-generation wireless communications.
