Hex to Number Online

Hex to Number Converter

This free and open-source tool allows you to easily convert hexadecimal (hex) numbers to their decimal equivalent. Hexadecimal is a base-16 number system commonly used in computing and digital systems.

What is Hexadecimal?

Hexadecimal is a numeral system that uses 16 distinct symbols. It uses the digits 0-9 and the letters A-F to represent values. In computing, hex is often used because it can represent every byte (8 bits) as two hexadecimal digits, making it more compact and readable than binary.

How to Use

  1. Enter a hexadecimal number in the input box (with or without the '0x' prefix).
  2. The tool will automatically convert it to its decimal equivalent.
  3. The result will appear in the output box.
  4. Click the "Copy" button to copy the decimal result to your clipboard.

Features

  • Real-time conversion from hexadecimal to decimal
  • Support for positive integers
  • Handles input with or without '0x' prefix
  • One-click copy to clipboard
  • Clear button to reset input and output

Use Cases

  • Converting hexadecimal values to decimal for programming tasks
  • Working with color codes in web development (Hex to RGB)
  • Analyzing memory addresses in computer science
  • Converting between number systems in mathematics and computer science education

How It Works

The converter processes the input by:

  1. Removing the '0x' prefix if present
  2. Iterating through each digit of the hex number
  3. Multiplying the current result by 16 and adding the value of the current digit
  4. Repeating until all digits are processed

Privacy and Security

This tool performs all conversions directly in your browser. No data is sent to any external server, ensuring that your information remains private and secure.

Note

While hexadecimal is widely used in computing, it's important to understand the context in which you're using these numbers. Always double-check your conversions, especially when working with critical systems or data.
