How this conversion works
Sixteen is 10000 in binary — a single 1 followed by four zeros. Powers of two are the round numbers of binary, each one just shifting that lone bit left.
Each base just uses a different set of digits for the same quantity. Reading
16 as a decimal number gives the decimal value
16; expressing that same value in base two, eight or sixteen
produces the rows above. To convert any number between bases — including custom bases from 2
to 36 — use the number base converter.
