How do you convert hexadecimal numbers into binary numbers?

Answer 1

Binary to hexadecimal is very easy because hexadecimal numbers are designed specifically so that each hex digit is exactly 4 bits (i.e. 16 different values). So if you had this binary number:

binary: 100011011011110101000100001

You could put in commas every four places (starting on the left):

binary: 100,0110,1101,1110,1010,0010,0001

Then you could write the hex values immediately below:

binary: 0100,0110,1101,1110,1010,0010,0001

hex: 4 6 D E A 2 1

and the hex value would be 46DEA21.
