About Number Base Converter
Need to convert a binary string into decimal, or a decimal into hexadecimal? The Number Base Converter is a fast, reliable, and user-friendly tool that handles all your number system conversion needs. Designed for developers, students, engineers, and hobbyists, it simplifies the math behind base conversions, whether you're learning base theory or debugging a binary sequence.
With support for multiple bases including binary (base 2), octal (base 8), decimal (base 10), and hexadecimal (base 16), this online base converter transforms values in real time with just a few clicks. It converts a number between bases, which is a different job from encoding text: text to binary and text to hex take characters and show you their codepoints, while this takes a value that is already a number and rewrites it. Both kinds sit with the site's number tools and encoding tools respectively. Whether you're studying number theory, working on embedded systems, or writing assembly-level code, this converter provides accurate, formatted outputs you can trust.

Supported Base Conversions
This tool supports the following base conversions:
- Binary (Base-2) to Decimal (Base-10)
- Decimal (Base-10) to Hexadecimal (Base-16)
- Octal (Base-8) to Binary (Base-2)
- Hexadecimal (Base-16) to Decimal (Base-10)
| From Base | To Base | Example |
|---|---|---|
| Binary (2) | Decimal (10) | 1010 → 10 |
| Decimal (10) | Hexadecimal (16) | 255 → FF |
| Octal (8) | Binary (2) | 17 → 1111 |
| Hexadecimal (16) | Decimal (10) | 7A → 122 |
