How this conversion works

One thousand in binary is ten bits long. The gap between the decimal "kilo" (1000) and the binary "kibi" (1024) starts exactly here and causes endless storage-size confusion.

Each base just uses a different set of digits for the same quantity. Reading 1000 as a decimal number gives the decimal value 1000; expressing that same value in base two, eight or sixteen produces the rows above.
