The hertz (or Hz) was a unit of frequency, where one hertz was equal to one cycle per second, used to describe ranges of sound, of the electromagnetic spectrum, and of brain waves.

Used in applications[]

Decihertz (10−1 Hz, dHz)
Hertz
Kilohertz (103 Hz, kHz)
Megahertz (106 Hz, MHz)

When the USS Voyager used a microprobe as a subspace communications relay to contact a Romulan science vessel through a micro-wormhole, B'Elanna Torres noted that the phase amplitude of the visual link with the ship was within a few megahertz of transporter protocols. (VOY: "Eye of the Needle")

Terahertz (1012 Hz, THz)

Three hundred twenty-seven systems that used terahertz feeds were known to the Federation in 2367, none of which were used by Starfleet. The forged Federation phaser rifles created by the Romulans, discovered on Krios Prime and used by Kriosian rebels, were charged with a forced pulse, well into the terahertz range. This range is similar with those found in Romulan disruptors, which create an inverted initial output spike, with corresponding discharge crystal and emission beam pattern. (TNG: "The Mind's Eye")
