Now, we can convert binary to HEX very easily

8 4 2 1

0 0 0 0 = 0

0 0

0 1 = 1

0 1 0 = 2

0 0 1 1 = 3

0 1 0

0 = 4

0 1 0 1 = 5

0 1

1 0 = 6

0 1 1 1 = 7

1 0 0 0 = 8

1 0

0 1 = 9

1 0 1 0 = A

1 0 1

1 = B

1 1 0 0 = C

1 0 1 = D

1 1

1 0 = E

1 1 1 1 = F

You seldom need to consider decimal numbers at all. Usually you can go directly from

binary to hex.

Get used to splitting the binary number into groups of four, with the Least Significant Bit

(LSB) on the right hand side. If you split it up, then - it doesn't matter how big it is - you

can always convert each group into hex and achieve the complete answer. Consider the

following 11 Bit number

1024 512 256

128 64 32 16 8 4 2 1

0 1 0

0 1

1 0 1

can be written as

8 4 2 1 8 4 2 1 8 4 2 1

0 1 0

0 1

1 0 1

= 2

+ 2 +1 + 8 + 2 +1

= 2 3 B

= 23B HEX

Since this was an 11 Bit number it could not be divided exactly into groups of four but, as

you see, it didn't matter. We ignore any bits missing at the

left hand side, as if they were

zero.
