## Speak the Language of Computers
Under the hood, every computer runs on binary (0s and 1s). But for humans, reading binary is painful. The **Number Base Converter** instantly translates numbers between the four most common systems used in computer science.
### Supported Systems
- **Decimal (Base 10)**: Our standard human counting system (0-9).
- **Binary (Base 2)**: The fundamental language of logic gates and processors.
- **Hexadecimal (Base 16)**: The standard for memory addresses, CSS colors, and IPv6 addresses.
- **Octal (Base 8)**: Common in Unix file permissions (e.g., `chmod 755`) and older computing systems.
### Cheat Sheet
- **Binary**: 1010
- **Decimal**: 10
- **Hex**: A
- **Octal**: 12
### Use Cases
- **Web Development**: translating RGB values (0-255) into Hex color codes (#FF0000).
- **Systems Programming**: Debugging memory dumps or analyzing network packets.
- **Students**: Checking homework for Computer Architecture 101.
Frequently Asked Questions
Why is Hex used so much?
Hexadecimal is a shorthand for binary. One Hex digit represents exactly 4 binary bits (a nibble). This makes it much more compact and easier to read than a stream of 0s and 1s.
What is the maximum number?
We support standard JavaScript safe integers (up to 2^53 - 1). For larger numbers, precision might be lost.
Can I convert text to binary?
No, this tool converts **mathematical values**. To turn the letter 'A' into binary (01000001), use our Text to Binary tool.
How do I calculate this manually?
To convert Binary to Decimal: Sum the powers of 2 for each '1' bit. E.g., 101 = (1*4) + (0*2) + (1*1) = 5.
