Hertz to Gigahertz 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 gigahertz (GHz) is a unit of frequency equal to one billion hertz (10⁹ Hz). It represents very high frequencies commonly found in microwave radiation, computer processors, and modern wireless communications.

The gigahertz became prominent with the development of microwave technology and high-speed electronics in the mid-20th century. It gained widespread recognition with computer processor speeds and became a household term with the advancement of personal computers and wireless technology.

Gigahertz is extensively used in computer processor specifications, wireless communications (WiFi, Bluetooth, cellular), microwave technology, and radar systems. It's standard for CPU clock speeds, wireless frequency bands, and microwave oven operating frequencies.
