decimal prefix binary prefix
Kilobyte (kB) 103 Byte = 1.000 Byte Kibibyte (KiB) 210 Byte = 1.024 Byte
Megabyte (MB) 106 Byte = 1.000.000 Byte Mebibyte (MiB) 220 Byte = 1.048.576 Byte
Gigabyte (GB) 109 Byte = 1.000.000.000 Byte Gibibyte (GiB) 230 Byte = 1.073.741.824 Byte
Terabyte (TB) 1012 Byte = 1.000.000.000.000 Byte Tebibyte (TiB) 240 Byte = 1.099.511.627.776 Byte
Petabyte (PB) 1015 Byte = 1.000.000.000.000.000 Byte Pebibyte (PiB) 250 Byte = 1.125.899.906.842.624 Byte
Exabyte (EB) 1018 Byte = 1.000.000.000.000.000.000 Byte Exbibyte (EiB) 260 Byte = 1.152.921.504.606.846.976 Byte
