Step 1: Split the Bits

Split the two hexadecimal numbers into single digits.

62
 
6 2

Step 2: Convert Digits to Denary

Convert each digit to denary.

For numbers 0 – 9, it will be the same. For numbers A – F, use 10 – 15.

6=6

6 less than 10, so it is the same in hexadecimal and denary.

2=2

2 less than 10, so it is the same in hexadecimal and denary.


Step 3: Convert to Binary Nibbles

Convert each denary digit into a nibble (a four-bit binary number).

6 =

8 4 2 1
0110

2 =

8 4 2 1
0010

Step 4: Join into a Byte

Put our two binary nibbles together to create one byte.

Remember to re-number the binary columns for the first nibble.

128 64 32 16   8 4 2 1
0110 0010

Step 5: Convert Binary to Denary

Finally, convert the whole binary byte into a decimal number.

128 64 32 16 8 4 2 1
01100010

64 + 32 + 2 = 98


The answer

We have now converted 6216 to 9810.

98
