How many megahertz in a gigahertz

One gigahertz represents 1 billion cycles per second. Clock speed, which is also measured in hertz, refers to synchronous circuit clock frequency, for example, a CPU. One clock cycle lasts only 1 nanosecond and toggles between 0 and 1. Modern and non-embedded CPUs may have a single clock cycle of less than 1 nanosecond.

CPU megahertz usually refers to clock rate, frequency or speed. Clock rate is gauged by a crystal oscillator which generates highly accurate and unwavering electrical and clock signals, stabilizes receivers and frequencies, and tracks time.

The oscillator circuit brings its crystal a small amount of electricity every nanosecond, which is measured in hertz. By: Justin Stoltzfus Contributor, Reviewer. By: Satish Balakrishnan.

Do you want to convert megahertz to gigahertz?

For example, here's how to convert 5 gigahertz to megahertz using the formula above. Gigahertz Gigahertz is a measure of frequency equal to one billion cycles per second.

Hertz is the unit used to measure the number of cycles of an oscillating body. The abbreviation MHz connotes Megahertz. MHz is the unit of measurement used to calculate the frequency of millions of clock time cycles completed per unit time.

It is a common Hertz multiplier used to calculate the periodic cycles of a microprocessor. One MHz is mathematically equivalent to 1,, hertz. A value in MHz can also be converted to GHz. However, one has to remember that megahertz is a smaller unit of measurement than gigahertz.

Hence, megahertz is related to gigahertz in the following way:. MHz is commonly used to measure the frequency of microprocessors. It is also infrequently used to measure radio waves, television broadcasting, bandwidths of hi-speed digital data transmissions, etc. MHz is frequently used to measure spread spectrum signals. Gigahertz and Megahertz are both used as clock speed measurement units.

They have very similar uses as both these units are used to measure the cyclical frequencies of processors, electromagnetic waves , frequency of sound waves, etc.
