Step 1: Split the Bits
Split the two hexadecimal numbers into single digits.
| 1 | 9 |
| 1 | 9 |
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.
| 1 | = | 1 |
1 less than 10, so it is the same in hexadecimal and denary.
| 9 | = | 9 |
9 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).
1 =
| 8 | 4 | 2 | 1 |
|---|---|---|---|
| 0 | 0 | 0 | 1 |
9 =
| 8 | 4 | 2 | 1 |
|---|---|---|---|
| 1 | 0 | 0 | 1 |
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 | |
|---|---|---|---|---|---|---|---|---|
| 0 | 0 | 0 | 1 | 1 | 0 | 0 | 1 |
Step 5: Convert Binary to Denary
Finally, convert the whole binary byte into a decimal number.
| 128 | 64 | 32 | 16 | 8 | 4 | 2 | 1 |
|---|---|---|---|---|---|---|---|
| 0 | 0 | 0 | 1 | 1 | 0 | 0 | 1 |
16 + 8 + 1 = 25
The answer
We have now converted 1916 to 2510.
25
