Number Base Converter

Convert numbers seamlessly between Decimal (Base 10), Hexadecimal (Base 16), Octal (Base 8), and Binary (Base 2).

Decimal (Base 10)
Hexadecimal (Base 16)
Octal (Base 8)
Binary (Base 2)

How to convert Number Bases

Type a valid number into any of the base fields (Decimal, Hexadecimal, Octal, or Binary). As you type, the other fields automatically populate with the converted equivalent.

Understanding Number Systems

While humans operate in Decimal (Base 10), computer systems fundamentally operate in Binary (Base 2). Hexadecimal (Base 16) is frequently used in programming as a human-friendly shorthand for binary, allowing developers to represent bytes concisely.

Practical Uses for Developers

Converting between bases is a routine task for developers working with low-level systems, memory addresses, color codes (like HTML HEX colors), network routing, and cryptography. This utility provides rapid, real-time conversion without needing to write custom parsing scripts.
