The prefixes for bits and bytes (kilo, mega, giga and tera) are in binary notation not common SI unit notation. For example, 1 kilobyte = 1024 bytes, 1 megabyte = 1024 kilobytes, 1 gigabyte = 1024 megabytes, etc. A more complete discussion about binary prefixes. In common SI notation, say for joules, 1 kilojoule = 1000 joules, 1 megajoule = 1000 kilojoules, 1 gigajoule = 1000 megajoules, etc.
