Arrange your binary number in Four number groups from right to left add zero's if needed. So if your binary is 11011101 it will be 1101 1101 now replace your group with 0-0000 1-0001 2-0010 3-0011 4-0100 5-0101 6-0110 7-0111 8-1000 9-1001 A-1010 B-1011 C-1100 D-1101 E-1110 F-1111 and you get your number in hex 1101 1101 == DD
1101 is the binary equivalent of the decimal number 13
9: 1001 10: 1010 11: 1011 12: 1100 13: 1101 14: 1110 15: 1111 16: 10000
10 = 1010, 11 = 1011, 12 = 1100, 13 = 1101, 14 = 1110, 15 = 1111, 16 = 10000.
