let us take a binary number.. say :

0000000110101110 (16 bit number)
we already know it's the consersion to HEXA DECIMAL equivalent.... so split the numbers into 4 bits each... like,

0000 0001 1010 1110 (16 bit number)

and for converting directly there is a conversion called 8421 code...

8421 | 8421 | 8421 | 8421
0000 | 0001 | 1010 | 1110

now in the first pass it is zero (from left to right) , second it is 1 , in third it is 10 (A in hexa.) , in fourth it is 14 (E in hexa.)


thus the final representation for the above binary is : 1AE
