Base Converter
Number Base Converter (Binary, Decimal, Hex, Octal) — What Is It?
A number base converter helps you instantly convert a value between different number systems. With this tool you can quickly switch between Binary (Base 2), Decimal (Base 10), Octal (Base 8), and Hexadecimal (Base 16). These conversions are common in programming, computer science, electronics, and networking, and doing them manually can be slow.
What Each Base Is Used For
- Decimal (Base 10): The standard system used in everyday life.
- Binary (Base 2): The language computers use internally (only 0 and 1).
- Octal (Base 8): Sometimes used in low-level systems and permission formats.
- Hexadecimal (Base 16): Widely used for memory addresses, color codes (like #FFAA00), and embedded systems.
How to Use This Base Converter
- Type a number into any input field (Decimal, Binary, Hexadecimal, or Octal).
- The tool automatically converts it and fills the other fields.
- Use the Copy button to copy any result with one click.
Examples (Quick Reference)
Here are a few simple examples: 255 in decimal equals 11111111 in binary, FF in hexadecimal, and 377 in octal. These quick checks are useful when working with bit operations, debugging, or reading system values.
Frequently Asked Questions
Is this tool free to use?
Yes. You can use the converter anytime to switch between bases instantly.
Why does hexadecimal use letters?
Hex uses 16 symbols: 0–9 and A–F. Letters represent values 10–15 to keep numbers shorter and easier to read.
What if my input is invalid?
The converter shows a warning for invalid formats (for example, binary should contain only 0 and 1).
