Gigabyte is often abbreviated as G or GB\n\nIn December 1998 the International Electrotechnical Commission (IEC), the leading international organization for worldwide standardization in electrotechnology, approved as an IEC International Standard names and symbols for prefixes for binary multiples for use in the fields of data processing and data transmission. The prefixes are as follows: \n\n\n--------------------------------------------------------------------------------\nPrefixes for binary multiples \n--------------------------------------------------------------------------------\n \n Factor  Name  Symbol  Origin Derivation  \n 210 kibi Ki kilobinary: (210)1 kilo: (103)1 \n 220 mebi Mi megabinary: (210)2  mega: (103)2 \n 230 gibi Gi gigabinary: (210)3 giga: (103)3 \n 240 tebi Ti terabinary: (210)4 tera: (103)4 \n 250 pebi Pi petabinary: (210)5 peta: (103)5 \n 260 exbi Ei exabinary: (210)6 exa: (103)6 \n \n\n--------------------------------------------------------------------------------\n \nExamples and comparisons with SI prefixes \none kibibit  1 Kibit = 210 bit = 1024 bit \none kilobit  1 kbit = 103 bit = 1000 bit \none mebibyte  1 MiB = 220 B = 1 048 576 B \none megabyte  1 MB = 106 B = 1 000 000 B \none gibibyte  1 GiB = 230 B = 1 073 741 824 B \none gigabyte  1 GB = 109 B = 1 000 000 000 B \n\n--------------------------------------------------------------------------------
