The Gigabyte = 1,024 Megabytes. We start with the lowly âbyteâ. In simplest terms, 1 byte is the amount of data needed to store 1 character (letter). If the average word is 6 characters long, then the average word is 6 bytes. For a 500-word essay, thatâs 3,000 bytes. You need 1,024 bytes to have 1 kilobyte (KB).
