Hexadecimal
- Hexadecimal or hex, is a base-16 numerical system using digits 0-9 and letters A-F to represent values 10-15.
- Widely used in computing, it provides a concise representation of binary data and simplifies tasks such as memory addressing color representation, and programming.
Decimal Number
- A decimal number is a numerical value expressed in the base-10 system, using digits 0 to 9.
- It represents quantities in everyday mathematics and is widely used in commerce, finance, and everyday calculations, with each digit's position representing a power of 10.

Example: Convert the hexadecimal number 3B to decimal.3 x 16^1 (3 * 16) = 48
B x 16^0 (11 * 1) = 11
48 + 11 = 59
Therefore, 3B (hex) is equal to 59 (decimal).
Hexadecimal to Decimal Conversion with Steps
As we know, Hexadecimal numbers use base-16, while decimal numbers use base-10.The conversion process follows positional values, just like decimal, but with powers of 16.
Step 1: Understand the Hexadecimal System
Hexadecimal is a base-16 number system that uses the symbols 0–9 and A–F, where A = 10, B = 11, C = 12, D = 13, E = 14, and F = 15.
Step 2: Identify Digit Positions
Each digit’s position is counted from right to left, starting at 0. For example, in 2A3, the positions are:
- 3 → position 0
- A → position 1
- 2 → position 2
Step 3: Multiply by Powers of 16
Multiply each digit’s decimal value by 16 raised to its position:
- 2 × 16²
- A (10) × 16¹
- 3 × 16⁰
Step 4: Add the Results
Add all the values to get the final decimal number:
(2 × 16²) + (10 × 16¹) + (3 × 16⁰) = 675
Example: Hexadecimal number: 3A7B
Calculation:
3 * 16^3 + A(10) * 16^2 + 7 * 16^1 + B(11) * 16^0
= 3 * 4096 + 10 * 256 + 7 * 16 + 11 * 1
= 12288 + 2560 + 112 + 11
= 14971
So, the decimal equivalent of hexadecimal 3A7B is 14971.
