🔢 Number Base Converter

Convert numbers between binary, octal, decimal, and hexadecimal.

How to Use the Number Base Converter

Converting between number bases is fundamental in computer science and programming. Here's how to use our converter:

  1. Enter Your Number: Type the number you want to convert in the value field. Use digits appropriate for your selected base (0-1 for binary, 0-7 for octal, 0-9 for decimal, 0-9 and A-F for hexadecimal).
  2. Select Source Base: Choose the base of your input number from the dropdown. Options include Binary (base 2), Octal (base 8), Decimal (base 10), and Hexadecimal (base 16).
  3. Convert: Click "Convert" to see your number in all four bases simultaneously. The results display in a clear, easy-to-read format.
  4. Use Results: Copy the converted values for use in your programming, documentation, or calculations. Each result is clearly labeled with its base.

Understanding Number Bases: Binary (base 2) uses only 0 and 1, fundamental to computer logic. Octal (base 8) was historically used in computing. Decimal (base 10) is our everyday number system. Hexadecimal (base 16) is widely used in programming for memory addresses and color codes.

Common Applications: Programmers use hexadecimal for color codes and memory addresses. Binary is essential for understanding computer logic and bit operations. Network engineers use octal for file permissions. This converter helps you work fluently across all these systems.
