Hertz (Hz):
This is the SI unit for the term frequency and is interpreted to represent one cycle per second, describing how often an event recurs in a one-second period.
It is universally applied in physics, audio, as well as in electronics to describe wave frequencies: for example, the frequencies of sound waves, radio waves, and alternating current.
Kilohertz (kHz):
Unit of frequency equal to 1,000 Hertz; this is often used to describe audio frequencies and radio broadcasting.
Use Case: Widespread usage is in telecommunications, radio broadcasting, and audio signal processing.
Megahertz:
Unit of Measurement: A unit of frequency equal to 1,000,000 Hertz. Megahertz is most commonly used to give a measure of the number of oscillations or cycles per second of any electromagnetic wave - from the very common radio, television, and microwaves.
Use case: Used in radio and TV broadcasting, wireless communication, and computer processors.
Gigahertz (GHz):
Description: A unit of frequency equal to 1,000,000,000 Hertz. It is often used in the measurement of extremely high frequencies, which are commonly used in modern communications technologies.
Application: It is evident in high-speed data transmission, satellite communication, radar, and computer CPUs clock speed.
Revolution per minute
Description: This is a unit that expresses the number of full rotations completed in one minute. It is a measure of rotational speed rather than frequency but is often used in many similar applications.
Use: The unit is often applied in automotive, engineering, and machinery industries to describe the rotational speed of engines and mechanical components.
Revolutions per second (rps):
Description: It is defined as the number of full rotations in a second. When talking about frequency, it is equivalent to Hertz.
Application: The device is utilized in high speed rotation measurement, such as in high performance motors, centrifuges, and other scientific studies that demand very precise measurements of rotational speed.
