FAQ

How does hexadecimal counting work?

Hexadecimal counting goes: 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F — then rolls to 10 (=16 decimal). Each position is worth 16× the previous. For example, 1F = 1×16 + 15 = 31 decimal. This is the basis of the in hexadecimal number system used in computing.

What is 16 bit in hex?

16 bit in hex means a 4-digit hex number ranging from 0000 to FFFF (0 to 65,535 in decimal). A 16-bit value uses exactly 4 hexadecimal digits, since each hex digit encodes 4 bits. For example, 0000 in hex = 0, and FFFF = 65,535.
