28 hexadecimal equals 40 decimal.
To convert 28 hexadecimal to decimal, each digit is multiplied by 16 raised to the power of its position, then summed up. The ‘2’ is in the 16^1 place and the ‘8’ in the 16^0 place. So, (2 × 16) + (8 × 1) = 32 + 8 = 40 decimal.
Conversion Result
When you convert 28 hexadecimal to decimal, the answer is 40. This shows that in decimal number system, the value of hexadecimal 28 becomes 40, which is easier to understand in everyday counting.

Conversion Formula
Hexadecimal to decimal conversion uses the formula: sum of each digit multiplied by 16 raised to its position power, starting from 0 on the right. For example, hex 2 8: (2 × 16^1) + (8 × 16^0) = 32 + 8 = 40. This works because each position represents a power of 16.
Conversion Example
- Convert hexadecimal 1A to decimal:
- Digits: 1 and A (which is 10 in decimal)
- Calculate: (1 × 16^1) + (10 × 16^0) = 16 + 10 = 26
- Convert hexadecimal 3F:
- Digits: 3 and F (15 in decimal)
- Calculate: (3 × 16^1) + (15 × 16^0) = 48 + 15 = 63
- Convert hexadecimal 7B:
- Digits: 7 and B (11 in decimal)
- Calculate: (7 × 16^1) + (11 × 16^0) = 112 + 11 = 123

Conversion Definitions
Hexadecimal is a base-16 number system using digits 0-9 and letters A-F, representing values 0-15, used mainly in computing for compactly expressing binary data. It simplifies binary representation by grouping bits into four.
Decimal is a base-10 number system using digits 0-9, the most common counting system globally, representing quantities in everyday life. It is the standard counting system used for general purposes and calculations.
Conversion FAQs
How do I convert hexadecimal 28 to decimal step-by-step?
First, identify each digit: 2 and 8. Then, multiply 2 by 16^1 which equals 16, and 8 by 16^0 which equals 8. Add these together: 16 + 8 = 24. But wait, in this case, hexadecimal 28 means 2×16 + 8, which equals 40 in decimal. Double-check the calculation for correctness.
Is there an easy way to convert any hexadecimal number to decimal without a calculator?
Yes, you can use the positional method: expand each digit by its place value (power of 16), then sum the results. Practice with small numbers helps, and you can write down the steps to avoid mistakes. Remember, each digit’s value depends on its position.
What does the letter A in hexadecimal represent in decimal?
The letter A in hexadecimal equals 10 in decimal. Hexadecimal digits go from 0-9 and then A-F, where A=10, B=11, up to F=15. This allows representing larger numbers compactly, especially in computer memory addressing and color codes.
Can hexadecimal 28 be converted to binary directly?
Yes, convert each hexadecimal digit to its 4-bit binary equivalent: 2 is 0010, 8 is 1000. Combining these gives 0010 1000, which is the binary form. This method is quick and useful for low-level programming or understanding data storage.
Why is understanding hexadecimal important in programming?
Hexadecimal simplifies binary data representation, making it easier for programmers to read, write, and debug code. It is essential in areas like memory addresses, color codes in web design, and low-level hardware interactions, where binary data is prevalent.
