It doesn't. MHZ is a measure of cycles or frequency. A Megabyte is a measure of storage capacity.
if you mean 1 gigahertz (GHz) equal to in Megabytes (Mb); then the answer is none; they are two different things!
The MHz is the speed of the memory, while the MB or GB is the capacity. Put much more stock in the capacity (MB or GB) than the speed.
These are two completely different units of measure. MHZ (megahertz) measures frequency as cycles per second. MB (megabytes) measures memory storage.
Personal computers typically had around 64 mb of memory in 1998. The memory was usually SDRAM that ran at a speed of 100 mhz.
In computer memory, this is entirely subjective based on your computer, your needs, and changing technology. Most modern computer memory is either DDR2 or DDR3. DDR2 averages from 800 MHz to 1066 MHz, or 6400 MB/s to 8500 MB/s. DDR3 can be from 6400 MB/s to as much as 17,600 MB/s. Typically, DDR2-1066 (8500 MB/s) is fine for most games, but of course faster is better.
The Gateway 600YGR notebook comes with 200-pin industry standard DDR-SODIMM sockets that can accept 128-megabyte (MB), 256-MB, or 512-MB 266-MHz DDRAM memory modules. The memory is expandable up to 1,024 MB
The specifications are memory chips and memory modules. The DDR PC3200 RAM is a popular choice when one has to specify in this specific memory equipment.
*Since A Megabyte is a unit of memory capacity and a gram is a unit of weight, there is no answer to this question. Memory doesn't have a specific weight.
The game Aveyond was developed by the platform Windows 98/Me/XP. It's processor is 300 MHz. The amount of memory it can store is 256 MB and the size of the game is 23 MB.
RAM is measured by it's speed in mHz, it's size in megabytes or gigabytes, and it's interface type (i.e. DDR2 or DDR3).
Giga-hertz (processor clock) and Mega-bytes (memory)
Is a memory of 256 Mb
