What Is the Unit for Frequency?
The unit for frequency in the International System of Units is hertz, which is abbreviated as Hz. One hertz is defined as a frequency of one cycle per second.
The clock rate of computer central processing units are measured in megahertz or gigahertz, which allow consumers to compare CPU performance. The transmission signals for Wi-Fi and Bluetooth networks are also measured in gigahertz; these network signals are generally in the ranges of 2.4 gigahertz or 5 gigahertz.
Radians per second are used as a unit to measure angular frequency. These units are used to quantify rotational speed, and an angular frequency of 2? radians per second is equal to 1 hertz.
