How many megabytes are in one gigabyte (GB)?

One gigabyte (GB) is equivalent to 1024 megabytes (MB) based on the binary system commonly used in computer science. This is because digital storage is based on powers of two, and in this system, 1 gigabyte is calculated as 2^10 megabytes, which equals 1024. Understanding this relationship is crucial for tasks such as data storage, memory calculations, and bandwidth assessments in network engineering. The other options represent multiples of megabytes that do not accurately reflect the conversion from gigabytes to megabytes.
