There are three definitions of megabyte (MB), two of which are commonly used in computing:

• 1000 Ã— 1000 = 1,000,000 bytes in a megabyte - This is the standard SI definition, used for most media measurements (like hard drives and DVDs), for networking, and in some software (like Mac OS X and Linux).
• 1024 Ã— 1024 = 1,048,576 bytes in a megabyte - This is the definition commonly used by memory manufacturers and in some software (like Microsoft Windows). The official term for this unit is "mebibyte" (MiB).
• 1024 Ã— 1000 = 1,024,000 bytes in a megabyte - This definition was used in the once-common "1.44 MB" floppy disk, and is usually considered a mistake

1 Kilobyte - 1024 bytes. 1 Megabyte - 1,048,576 bytes.

1048576 bytes.1 Kilobyte(KB)=1024 bytes and 1 Megabyte(MB)=1024 kilobytes.So 1MB=1024x1024 bytes.

1000 bytes is a megabyte. 1000 megabytes is a gigabyte. Therefore, a gigabyte is 1,000,000 bytes

659,456 bytes equates to 0.63 (0.62890625) MB
