Nach '''ISO 1000:1992''' steht die Vorsilbe "Giga" für das 10-hoch-9-fache einer Grundeinheit. Demnach ist z.B. 1 Gigabyte = 1.000.000.000 Byte.
 
 
 
In der IT wird dagegen gerne definiert: "1 Gigabyte = 1024 Megabyte, 1 MB = 1024 kB, also 1 GB = 2<sup>30</sup> Byte" dies ist aber inkorrekt.
 
 
 
Noch nicht sehr vebreitet ist die Normung solcher "binären Vorsilben" durch die IEC: '''Gibi'''byte (GiB).  
 
Damit ist "1 GiB = 2<sup>30</sup> Byte = 1.073.741.824 Byte" endlich richtig.
 
 
 
1 GiB sind also 7,37% weniger als 1 GB.
 
 
 
In December 1998, the IEC produced new prefixes for binary multiples: kibibytes (KiB), mebibytes (MiB), gibibytes (GiB), tebibytes (TiB), and so on. (More details at NIST, also released as IEEE Std 1541-2002) These prefixes may never catch on, or they may cause even more confusion, but they are a valiant effort to solve the problem. The big strike against them is that they sound rather silly.
