Base Converter — Binary, Octal, Decimal & Hexadecimal
Base Converter converts numbers between binary, octal, decimal, hexadecimal, and other bases. Enter a value, choose its base, and instantly see the equivalent in every other base — perfect for programming and low-level debugging.
Features & Usage Tips
Enter a number in any base (binary, octal, decimal, hex, and more) to instantly see its equivalent in all other bases.
Number Bases Explained
A number base determines the digits and place values used to represent a value: binary uses 0-1, octal 0-7, decimal 0-9, and hexadecimal 0-9 plus A-F. Converting between bases is fundamental in programming, networking, and computer architecture.
- Input Base: Choose the base of the value you type — binary, octal, decimal, hexadecimal, or custom bases up to 36.
- Instant Results: The equivalent value in every common base is shown immediately as you type.
- One-click Copy: Copy any result with a single click for use in code or documentation.
Use Cases
💻 Programming: Convert between decimal and hex when reading memory dumps, color codes, or file permissions.
🌐 Networking: Work with IP addresses, subnet masks, and MAC addresses in binary and hex.
🧮 Computer Science: Practice and verify base conversions for coursework or interviews.
🔧 Debugging: Decode hex-encoded values from logs, binary data, or serial output.
