Exahertz Unit | All you need to know
The exahertz (symbol: EHz) is an SI-derived unit of frequency equal to one quintillion (1018) hertz. It is an extremely large unit used primarily in theoretical physics, spectroscopy, astrophysics, and advanced scientific research involving extremely high-frequency electromagnetic waves. The exahertz uses the SI prefix exa, representing a factor of 1018.
One exahertz is equal to 1,000 petahertz, 1,000,000 terahertz, 1,000,000,000 gigahertz, 1,000,000,000,000 megahertz, and 1×1018 hertz. Although rarely encountered in everyday applications, the exahertz is useful for expressing exceptionally high frequencies in scientific calculations.
