MHz is the abbreviation for the word "megahertz," which is a unit of measurement for frequency in science. One cycle per second is measured as one hertz (Hz), and 1 MHz is equal to 1 million Hz. Frequency is important in measuring a wide range of electromagnetic signals and waves, including available bands for radio broadcasts and clock speeds in computers.
Hertz can be used in the singular or the plural. It is the common unit of measurement for frequency, counting the number of cycles completed in one second. In fact, before the implementation of the term "hertz," the measurement was actually called “cycles per second” (cps) and MHz were called "megacycles." One MHz denotes one million hertz or one million cycles per second, and also equals 1,000 kilohertz (KHz). These different unit sizes are used in various fields, such as radio broadcasting and computer science.
What comes after MHz?
When measuring the frequency (speed) of a CPU (central processing unit), GHz (gigahertz) comes after MHz.
What comes before MHz?
When measuring the frequency (speed) of a CPU (central processing unit), kHz (kilohertz) comes before MHz.
