AN!Wiki :: IEC and SI Size Notations |
How data sizes are shortened varies depend on whether the program or author is using base2 and base10 notation. The short-form notation followed by it's English long-form name for each type is listed below. Then it shows in the braces the X to the power of Y value that it represents followed, finally, by the exact number of bytes represented.
base2 Notation
IEC Notation Size -------------- ------------------------------------------------- KiB = kibibyte (2^10 / 1,024 bytes) MiB = mebibyte (2^20 / 1,048,576 bytes) GiB = gibibyte (2^30 / 1,073,741,824 bytes) TiB = tebibyte (2^40 / 1,099,511,627,776 bytes) PiB = pebibyte (2^50 / 1,125,899,906,842,624 bytes) EiB = exbibyte (2^60 / 1,152,921,504,606,846,976 bytes) ZiB = zebibyte (2^70 / 1,180,591,620,717,411,303,424 bytes) YiB = yebibyte (2^80 / 1,208,925,819,614,629,174,706,176 bytes)
base10 Notation
SI Notation Size -------------- ------------------------------------------------- KB = kilobyte (10^3 / 1,000 bytes) MB = megabyte (10^6 / 1,000,000 bytes) GB = gigabyte (10^9 / 1,000,000,000 bytes) TB = terabyte (10^12 / 1,000,000,000,000 bytes) PB = petabyte (10^15 / 1,000,000,000,000,000 bytes) EB = exabyte (10^18 / 1,000,000,000,000,000,000 bytes) ZB = zettabyte (10^21 / 1,000,000,000,000,000,000,000 bytes) YB = yottabyte (10^24 / 1,000,000,000,000,000,000,000,000 bytes)
