Conversion Formula
The formula to convert hexadecimal to decimal involves multiplying each digit by its positional value based on power of 16. Starting from the right, each digit is multiplied by 16 raised to its position index, then summed up. For example, for 28: (2×16^1) + (8×16^0) = 32 + 8 = 40.
This works because hexadecimal is base-16, meaning each digit represents a power of 16. The leftmost digit is multiplied by 16 raised to one less than the total number of digits, and so on, summing all to get the decimal equivalent.
Conversion Example
- Hexadecimal 3A:
- 3 in the sixteens place: 3×16 = 48
- A (which is 10) in the ones place: 10×1 = 10
- Sum: 48 + 10 = 58
- Hexadecimal 7F:
- 7 in the sixteens place: 7×16 = 112
- F (which is 15) in the ones place: 15×1 = 15
- Sum: 112 + 15 = 127
- Hexadecimal 1B:
- 1 in the sixteens place: 1×16 = 16
- B (which is 11) in the ones place: 11×1 = 11
- Sum: 16 + 11 = 27
