In the context of computing, the metric prefixes are often intended to mean something other than their normal meaning. For example, a kilobyte is actually 1024 bytes even though the standard meaning of kilo is 1000. And, mega normally means one million, but in computing is often used to mean 2 20 = 1 048 576. The table below illustrates the ...
The prefixes from tera-to quetta-are based on the Ancient Greek or Ancient Latin numbers from 4 to 10, referring to the 4th through 10th powers of 10 3. The initial letter h has been removed from some of these stems and the initial letters z , y , r , and q have been added, ascending in reverse alphabetical order, to avoid confusion with other ...

According to these standards, kilo, mega, giga, et seq. should only be used in the decimal sense, even when referring to data storage capacities: kilobyte and megabyte denote one thousand and one million bytes respectively (consistent with the metric system), while terms such as kibibyte, mebibyte and gibibyte, with symbols KiB, MiB and GiB ...

In some fields of computing, mega may sometimes denote 1 048 576 (2 20) information units, for example, a megabyte, a megaword, but denotes 1 000 000 (10 6) units of other quantities, for example, transfer rates: 1 megabit/s = 1 000 000 bit/s. In the case of 3½-inch floppy disks, sizes were given in megabytes of 1000KB or 1 024 000 bytes. [2]
