When looking at computers, you may see the performance metrics of some components being listed in MHz.
The unit MHz is made up of two parts: M and Hz.
M is simply the SI prefix for Mega, meaning million.
Hz, pronounced Hertz, is an SI unit that is defined as cycles per second.
Combined that means that MHz is a measure of millions of cycles per second.
Higher numbers are faster as more cycles are completed per second.
In GHz, the G stands for Giga, meaning billion, so 1 GHz = 1000 MHz.
