The reverse of the procedure is easier than it seems, too. Given a hex value of 0xC4, all we need to do is to first convert to binary, and then to decimal.

To convert to binary, take the two hex characters and find their binary value:

C = 1100 0100 = 4

Now, make the two 4-bit strings into one 8–bit string:

11000100

Finally, add the bit values of the columns where you have a 1:

128 + 64 + 4 = 196
