kilohertz [kHz] to gigahertz [GHz] Converter

Quick Reference

1 kilohertz (kHz) = 1.0000e-6 gigahertz (GHz)

1 gigahertz (GHz) = 1000000 kilohertz (kHz)

How to Convert kilohertz to gigahertz

1 kHz = 0.000001 GHz
1 GHz = 1000000 kHz

To convert kilohertz to gigahertz, divide the value by 1000000 (equivalently, multiply by 1.0000e-6). To convert gigahertz back to kilohertz, multiply by 1000000.

Example: convert 10 kHz to GHz:
10 kHz = 10 x 0.000001 = 0.000009999999999999999 GHz

kilohertz

Definition: A kilohertz (symbol: kHz) is a unit of frequency equal to one thousand (1000) hertz (Hz). The hertz, in turn, is the SI unit of frequency, defined as one cycle per second.

History/origin: The kilohertz is derived from the hertz, named after the German physicist Heinrich Hertz, who made significant contributions to the understanding of electromagnetic waves. The prefix 'kilo-' denotes a factor of 10<sup>3</sup>, adhering to the SI system of units.

Current use: Kilohertz is used to measure frequencies in the range of audio signals, radio waves (particularly AM radio), and some computer hardware components. It is a common unit in electronics, telecommunications, and signal processing.

gigahertz

Definition: A gigahertz (symbol: GHz) is a unit of frequency equal to one billion (1,000,000,000) hertz (Hz). The hertz, in turn, is the SI unit of frequency, defined as one cycle per second.

History/origin: The gigahertz is derived from the hertz, named after the German physicist Heinrich Hertz, who made significant contributions to the understanding of electromagnetic waves. The prefix 'giga-' denotes a factor of 10<sup>9</sup>, adhering to the SI system of units.

Current use: Gigahertz is primarily used to measure the clock speeds of modern computer processors, the frequencies of wireless communication technologies (e.g., 5G cellular networks), and radar systems. It represents very high-frequency signals and operations.
