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)
