Megahertz is used to measure wave frequencies, as well as the speed of microprocessors.
Megahertz. One megahertz is equal to one million cycles per second. It is used to measure transmission speeds of electronic devices. The most common area you will see Megahertz used is in measuring processor clock speed, such as an 800 Mhz Pentium III.  In computers, hertz is a measurement of cycles per second. Megahertz is just a way to lower the number, similar to meter vs. kilometer. This originally pertained to radio waves and sound waves, but is now commonly used to measure the speed of a computer processor (the number of hertz is equal to the number of clock ticks that a processor will have in one second). Megahertz. One megahertz (abbreviated: MHz) is equal to 1,000 kilohertz, or 1,000,000 hertz. It can also be described as one million cycles per second. Megahertz is used to measure wave frequencies, as well as the speed of microprocessors. Radio waves, which are used for both radio and TV broadcasts, are typically measured in megahertz. For example, FM radio stations broadcast their signals between 88 and 108 MHz. When you tune to 93.7 on your radio, the station is broadcasting at a frequency of 93.7 MHz. Megahertz is also used to measure processor clock speeds. This measurement indicates how many instruction cycles per second a processor can perform. The hertz (symbol Hz) is the unit of frequency in the International System of Units (SI) and is defined as one cycle per second. It is named for Heinrich Rudolf Hertz, the first person to provide conclusive proof of the existence of electromagnetic waves. Radio frequency radiation is usually measured in kilohertz (kHz), megahertz (MHz), or gigahertz (GHz). Light is electromagnetic radiation that is even higher in frequency, and has frequencies in the range of tens (infrared) to thousands (ultraviolet) of terahertz. In English, hertz is also used as the plural form. As an SI unit, Hz can be prefixed; commonly used multiples are kHz (kilohertz, 10 3 Hz), MHz (megahertz, 10 6 Hz), GHz (gigahertz, 10 9 Hz) and THz (terahertz, 10 12 Hz). Radio frequency radiation is usually measured in kilohertz (kHz), megahertz (MHz), or gigahertz (GHz). Light is electromagnetic radiation that is even higher in frequency, and has frequencies in the range of tens (infrared) to thousands (ultraviolet) of terahertz. Report Abuse. In computers, hertz is a measurement of cycles per second. Megahertz is just a way to lower the number, similar to meter vs. kilometer. In case you're wondering, a cycle is how long it takes for a processor to compute a machine code level instruction, or some instruction it receives in binary code. This originally pertained to radio waves and sound waves, but is now commonly used to measure the speed of a computer processor (the number of hertz is equal to the number of clock ticks that a processor will have in one second). Abbreviation for megahertz. One MHz represents one million cycles per second. The speed of microprocessors, called the clock speed, is measured in megahertz. For example, a microprocessor that runs at 200 MHz executes 200 million cycles per second. 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.. (M ega H ert Z) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (1, 4, 8, 16, 32 or 64) can be manipulated at least one million times per second. A two-gigahertz clock (2 GHz) means at least two billion times. The at least is because multiple operations often occur in one clock cycle. Both megahertz (MHz) and gigahertz (GHz) are used to measure CPU speed. For example, a 1.6 GHz computer processes data internally (calculates, compares, copies) twice as fast as an 800 MHz machine. Clock speed is measured in megahertz (MHz), millions of cycles per second, or in gigahertz (GHz), billions of cycles per second. Hertz is a unit of frequency, representing one cycle per second. 1 Megahertz is 1 million cycles per second. 2 people found this useful. Edit.
