About Frequency
A frequency is a quantity equal to the number of times a repeated event takes place in a given interval of time. In physics and engineering, it typically means waves, vibration, or rotation.
- Hertz (Hz) – The SI unit of frequency; 1 Hz = 1 cycle per second.
- Kilohertz (kHz), Megahertz (MHz), Gigahertz (GHz) – Applied to audio, radio, and wireless communications.
- Revolutions per minute (RPM) – Used for engines, and rotating equipment.
- Cycles per second (cps) – Same as hertz; previously used.
- Radian per second (rad/s) – Angular frequency of circular motion.
- Degree per second (°/s) – Angular velocity in degrees.
Frequency Units
Frequency is a fundamental unit that is utilized to measure how many times an event that recurs takes place in a unit of time. It has extensive use in physics, telecommunications, signal processing, and engineering.
The most common unit of frequency is the Hertz (Hz), which represents one cycle per second. Multiple units such as Kilohertz (kHz), Megahertz (MHz), Gigahertz (GHz), and Terahertz (THz) are used for more than a single cycle per second for ranges from thousands to trillions of cycles per second. These units are extensively employed in electronics, radio communication, and in the field of physics called optics.
For rotational systems, frequency is commonly defined in Revolutions per minute (RPM) or Revolutions per second (RPS), and is the rate of full circles an object is through in the given time.
There are also Cycles per second (cps), which is virtually equivalent to Hertz but sometimes used in specific technical contexts.
Angular frequency is in terms of Radian per second (rad/s), the angle traversed per second, a form most convenient in physics and mechanical engineering.
Lastly, Degree per second (°/s) is angular velocity in terms of degrees traversed per second, used most commonly in navigation and measurement of motion.
All these units of frequencies together constitute a set of practical measures to accurately describe oscillations, rotations, and cyclic processes in all branches of science and engineering.
