Gigabytes Definition
Gigabyte (GB) is one of the most commonly used units of digital information which is equal to 1,000,000,000 bytes. However, in computer operating science, the value of 1 GB is considered to be equal to 230 or 10243 bytes which is equal to 1,073,741,824 bytes. GB is often used for indicating a size of memory or specifying a size of a movie, computer RAM, and so on. The maximum amount of information stored in a single layer DVD is usually close to 4.8 GB, and the maximum amount of information that can be stored in a single layer Blu-ray disc is equal to 25 GB.
Gigabyte in SI and base 10 (decimal) 1 Gigabyte = 10003 bytes 1 Gigabyte = 1,000,000,000 bytes Gigabyte in base 2 (binary) 1 Gigabyte = 230 bytes 1 Gigabyte = 10243 bytes 1 Gigabyte = 1,073,741,824 bytes
Megabytes Definition
Megabyte (MB) is a unit of transferred or stored digital information, which is extensively used in information and computer technology. In SI, one megabyte is equal to 1,000,000 bytes. At the same time, practically 1 megabyte is used as 220 B, which means 1,048,576 bytes. Nowadays, the amount of information measured by megabytes is used for representing the size of a typical MP3 file, the size of a JPEG image, and so on.
Megabyte in SI and base 10 (decimal) 1 Megabyte = 10002 bytes 1 Megabyte = 1,000,000 bytes Megabyte in base 2 (binary) 1 Megabyte = 220 bytes 1 Megabyte = 10242 bytes 1 Megabyte = 1,048,576 bytes
How to Calculate Gigabytes to Megabytes?
Gigabyte in SI 1 Gigabyte = 10003 bytes We know that 1MB = 10002 bytes, so 1 Gigabyte = 1,000 * 1MB 1 Gigabyte = 1,000 Megabytes Gigabyte in base 2 1 Gigabyte = 230 bytes 1 Gigabyte = 10243 bytes We know that 1MB = 10242 bytes, so 1 Gigabyte = 1024 * 10242 bytes 1 Gigabyte = 1024 * 1MB 1 Gigabyte = 1024 MB 1 Gigabyte = 210 megabytes

- 64GB ssd = 64000 MB
- 128GB ssd = 128000 MB
- 256GB hdd = 256000 MB
- 512GB hdd = 512000 MB
- 2GB USB flash drive = 2,000 MB.
- A single layer DVD disc capacity is 4.7 GB = 4700 MB.
- A dual-layered DVD disc capacity is 8.5 GB = 8500 MB.
- A single layer Blu-ray disc capacity is 25 GB = 25,000 MB.
Even we calculate both decimal and binary value of megabytes from gigabytes,
please note that the SI recommends to use the definition 1GB = 1000MB which is equal to 10003 bytes.

thanks to teach us all about these bytes,b'se they have been confusing many p'ple. ...
The reason there are 1024 bytes in a kilobyte, and 1024 Kb in a Megabyte, and 1024 Mb in a Gigabyte, is because long ago when they first invented computers and they needed a way to address each byte in memory, they used 12 bits 1111 1111 1111 to hold the address number of each byte in memory. So 000000000001 is byte 1, and 111111111111 is byte 1024. To only use 1000 bytes would have been wasteful of the addressing capability, and in those days every byte counted.Now when we work with Gigs it is not usually so important to notice that there are some extra Megs over the 1000Mb count. Who cares, most of the time. But you must understand that even if you only count in 1000s, and not in 1024s, the extra ones are still there.So for example if you wanted to map 16G of memory to disk, and you had to size the disk file in M, if you sized it as 16,000M, and then copied the memory to the disk file, you would fail. Because the memory is actually 16384 Mb long.But usually we are working with rough amounts of space, not exact, so it doesn't matter. ...

All explanations are in httpsen.wikipedia.orgwikiIEEE1541-2002IEEE 1541 recommends a set of units to refer to quantities used in digital electronics and computing bit symbol 'b', a binary digit byte symbol 'B', a set of adjacent bits usually, but not necessarily, eight operated on as a group octet symbol 'o', a group of eight bits a set of prefixes to indicate binary multiples of the aforesaid units kibi symbol 'Ki', 210 1024 mebi symbol 'Mi', 220 1048576 gibi symbol 'Gi', 230 1073741824 tebi symbol 'Ti', 240 1099511627776 pebi symbol 'Pi', 250 1125899906842624 exbi symbol 'Ei', 260 1152921504606846976 that the first part of the binary prefix is pronounced as the analogous SI prefix, and the second part is pronounced as bee that SI prefixes are not used to indicate binary multiples.The bi part of the prefix comes from the word binary, so for example, kibibyte means a kilobinary byte, that is 1024 bytes. ...
