HEX
FOR DUMMIES
What is Hex?
Why is hex better then binary?
CONVERTING
Divide your number by 16, (example 145/16 = 9.0625) and that is your first digit (9). Then take away/find the difference between the number you get when you multiply 16 by 9 (example) and the number you want (145-144=1) second digit is 1. now try 123 and 17. if the number is only 1 digit it only needs the second number.

Hex to Denary
You multiply the first digit by 16 (4A so 4x16 = 64) and then you add the last digit (10) so its 74. Now try FD and 3E. oʍʇ ʎʇxıs puɐ ǝǝɹɥʇ ʎʇɟıɟ puɐ pǝɹpunɥ oʍʇ
Binary (8 bit) to hex
Work out the number in denary and then follow the other steps above. Try 01111111 and 0000111. uǝʌǝs puɐ 'uǝʌǝs ʎʇuǝʍʇ puɐ pǝɹpunɥ ǝuo
Hex To binary
work out the hex to deciaml and then convert to binary. Try 6D and DE. oʍʇ ʎʇuǝʍʇ puɐ pǝɹpunɥ oʍʇ ˙ǝuıu puɐ pǝɹpunɥ ǝuo
