HEX to Decimal
Hexadecimal (HEX) and decimal are two commonly used number systems in computing and programming. A HEX to Decimal tool is a utility that converts hexadecimal numbers (base-16) into their decimal (base-10) equivalents. This conversion is essential for developers, engineers, and students working with low-level programming, digital systems, and color codes.

What is Hexadecimal?
Hexadecimal is a base-16 numbering system that uses 16 symbols:
-
Digits:
0to9 -
Letters:
A(10) toF(15)
Example:
-
1A(HEX) =1 × 16¹ + 10 × 16⁰ = 16 + 10 = 26(Decimal)
Why Use a HEX to Decimal Tool?
-
Programming & Debugging
-
Helps in interpreting memory addresses, bitwise operations, and register values.
-
Useful in languages like C, C++, and assembly where hexadecimal is frequently used.
-
-
Web Development
-
Converts HEX color codes (e.g.,
#FF5733) to RGB decimal values.
-
-
Networking & Hardware
-
Used in MAC addresses, IPv6, and microcontroller programming.
-
-
Educational Purposes
-
Simplifies learning number system conversions.
-
How Does a HEX to Decimal Tool Work?
The tool follows a simple conversion algorithm:
-
Input: Accepts a HEX string (e.g.,
"2F"). -
Conversion:
-
Splits the HEX into digits.
-
Multiplies each digit by
16ⁿ(wherenis its position from right, starting at 0). -
Sums up the results.
-
-
Output: Returns the decimal equivalent (e.g.,
2F→47).
Example:"3E8" (HEX) → 3×16² + 14×16¹ + 8×16⁰ = 3×256 + 14×16 + 8×1 = 1000 (Decimal).
Features of a Good HEX to Decimal Tool
✅ Fast & Accurate Conversion – Instantly converts without errors.
✅ Supports Large Values – Handles 32-bit or 64-bit HEX numbers.
✅ Case-Insensitive – Works with "a1" or "A1".
✅ Copy-Paste Functionality – Easy input/output handling.
✅ Error Handling – Detects invalid HEX characters (e.g., "G", "Z").
Online vs. Offline HEX to Decimal Tools
