- F represents 15, in the 1’s place, so 15×1 = 15.
- Add: 48 + 15 = 63.
- Convert hexadecimal 1A to decimal:
- 1 in the 16’s place: 1×16 = 16.
- A equals 10, in the 1’s place: 10×1 = 10.
- Sum: 16 + 10 = 26.
- Convert hexadecimal B4 to decimal:
- B is 11 in the 16’s place: 11×16 = 176.
- 4 in the 1’s place: 4×1 = 4.
- Total: 176 + 4 = 180.

Conversion FAQs
Why does hexadecimal 28 equal 40 in decimal?
This is because each digit in hexadecimal is multiplied by 16 raised to its position power. For 28, 2 is in the 16’s place, so 2×16=32, and 8 is in the 1’s place, so 8×1=8. Adding these gives 40.
Can I convert hexadecimal to decimal without any tools?
Yes, by understanding the place value system, you multiply each digit by 16 raised to its position power, then sum the results. Practice makes this process quicker and easier to do manually.
What is the significance of the digits A-F in hexadecimal?
Digits A-F represent decimal values 10-15. They allow hexadecimal to compactly express larger numbers with fewer digits, making it easier for programmers to work with binary data.
How do I convert larger hexadecimal numbers to decimal?
Break down each digit, multiply by 16 raised to its position, and sum all. For larger numbers, follow the same process, starting from the rightmost digit and moving left.
Is hexadecimal conversion reversible?
Yes, converting back from decimal to hexadecimal involves dividing the decimal number by 16 repeatedly and noting remainders, which become the hexadecimal digits from last to first.
