If you have 10 address pins on a memory chip you get a total of 2 10 addresses on that chip. It comes from how computer memory is built and addressed (yes, we are talking electrical circuit level stuff) and on that level it only makes sense that memory is built in such a way that its size (number of addressable units) scales with powers of two. So: Storage capacity data units (binary) Unitīut why multiples of 1024, you might ask? It's because in a binary system every unit, no matter how big, is a power of 2, and 1024 is 2 10, unlike a decimal system where it is a power of 10. In the standard binary system, you have KiloByte, MegaByte, GigaByte, TeraByte, PetaByte and so on, all being derived as the smaller unit multiplied by 1024. Initially there were other systems with 10-bit Bytes, but these are not really in use today. The term was coined by Werner Buchholz in June 1956, during the early design phase for the IBM Stretch early computer. ![]() ![]() From it, all other data units are derived, according to two competing systems, the commonly used binary system and the standard, but not so commonly used system of the SI (International System of Units) - more on this in point 3 below.Īll data storage units are derived from the bit, with the fundamental unit for data storage being the 8-bit Byte (1 Byte = 8 bits). A bit is the smallest amount of information you can write to a storage device, it is either 1 or 0 on all binary systems, which is most of the systems we have to date. Storage of digital data on any kind of device: the now forgotten floppy disks, almost forgotten CD-ROMs, DVDs, as well as hard disk drives (HDD), solid state drives (SSD), thumb drives (USB sticks) is measured in a fundamental unit: the bit. Storage capacity & memory capacity data unitsĪ lot of people use this data unit converter to calculate storage capacity or memory capacity. Mixed and unorthodox conversions are supported as well, such as MB/s to mbps and mbps to megabytes per second. This tool supports pure data conversions such as from MB to GB, GB to MB, GB to TB, TB to GB, MB to KB, etc., as well as bandwidth conversions: mbps to kbps, mbps to gbps.
