Number Base Converter for Binary to Decimal & Hex Conversion
Instantly convert numbers between binary, octal, decimal, and hexadecimal formats with our free online radix converter. Perfect for developers, programmers, and computer science students who need quick, accurate number system conversions for coding, debugging, and data analysis.
Convert numbers between decimal, binary, octal, and hexadecimal number systems.
Understanding Number Base Systems: A number base (or radix) defines how many unique digits are used to represent numbers. Binary (base 2) uses 0-1 and is fundamental to computer architecture. Octal (base 8) uses 0-7 and was historically popular in computing. Decimal (base 10) uses 0-9 and is our everyday number system. Hexadecimal (base 16) uses 0-9 and A-F, widely used in programming for memory addresses, color codes, and compact data representation.
Common Use Cases: Binary to decimal conversion for interpreting bit patterns and machine code; hex to decimal for debugging memory addresses and assembly code; decimal to binary for bitwise operations and embedded systems programming; decimal to hex for RGB color values and low-level data inspection; octal for Unix file permissions and legacy systems. Our converter handles all bidirectional conversions instantly.
Features: Real-time conversion, large number support, copy individual results.
How to Use: Enter any number in its native base format into the corresponding field (binary, octal, decimal, or hexadecimal), and all other bases update automatically. The converter intelligently validates input for each base: binary accepts only 0-1, octal 0-7, decimal 0-9, and hexadecimal 0-9 and A-F. Click the copy button to quickly transfer any result to your clipboard. Perfect for developers working with bit-level operations, system programmers analyzing memory dumps, and students learning computer architecture fundamentals.
