Let's see an example. Hexadecimal number is 3A7 :
- 7 is 7 in decimal
- A is 10 in decimal
- 3 is 3 in decimal
- Assign positional values from right to left
- 7 (16^0)
- A (16^1)
- 3 (16^2)
- Multiply each digit by its positional value:
- 7 * 1 = 7
- 10 * 16 = 160
- 3 * 256 = 768
- Sum of the values : 7 + 160 + 768 = 935
The hexadecimal number 3A7 is equivalent to the decimal number 935.
