Converting binary to hexadecimal by hand

One hexadecimal digit is exactly four binary digits. Split the binary number into groups of four from the right (adding zeros in front if needed) and replace each group with its hex digit, or the other way round:

1101₂ 0110₂ → D 6
11010110₂ = D6₁₆

Binary and hexadecimal explained

Binary is base 2: it uses only the digits 0 and 1, and each position is worth twice the one to its right. It is how computers store every number, character and pixel.

Hexadecimal (hex) is base 16: the digits 0 to 9 plus A to F for the values 10 to 15. One hex digit is exactly four bits, so a byte is always two hex digits, as in colors (#FF8800) and memory addresses.
