The difference between megabytes and gigabytes is the number of bytes that make up each unit and the amount of data they hold. A megabyte holds a million bytes, or about 1,000 kilobytes. A gigabyte holds about a billion bytes, or around 1,000 megabytes. Continue Reading.
A kilobyte in binary is 1024 bytes(2 10), but it also used to refer to 1000 bytes (the decimal interpretation). This is where things start to get really confusing! You can see that a binary KB is slightly bigger than a decimal KB. A megabyte in binary is 1,048,576 (2 20) bytes. In decimal itâs 1,000,000 bytes (10 6). A gigabyte is either 2 30 (1073741824) bytes or 10 9 (1 billion) bytes. By now the difference between the binary version and the decimal version is quite significant.
