It's 8. (Next time you can use calc.exe of your windows.)
Each hexadecimal digit (or nybble) is the equivalent of 4 binary digits (or bits) with a decimal value of 0-15. Convert each nybble into (4) binary (digits) and string them together, remembering the conversion of decimal 0-15 to binary: Hex -> Dec -> Binary 0 -> 00 -> 0000 1 -> 01 -> 0001 2 -> 02 -> 0010 3 -> 03 -> 0011 4 -> 04 -> 0100 5 -> 05 -> 0101 6 -> 06 -> 0110 7 -> 07 -> 0111 8 -> 08 -> 1000 9 -> 09 -> 1001 A -> 10 -> 1010 B -> 11 -> 1011 C -> 12 -> 1100 D -> 13 -> 1101 E -> 14 -> 1110 F -> 15 -> 1111 So to convert 0x6AF to binary: 6 -> 0110 A -> 1010 F -> 1111 => 0x6AF = 0110 1010 1111 = 011010101111 (without the spaces showing the hex nybbles)
