About Number Base Conversion
What is a Number Base?
Number bases (or numeral systems) are ways to represent numbers using a specific set of digits. The most common is decimal (base 10) which uses digits 0-9, but other bases are important in computing.
Common Number Bases
- Decimal (Base 10): Uses digits 0-9
- Binary (Base 2): Uses only 0 and 1
- Hexadecimal (Base 16): Uses 0-9 and A-F
- Octal (Base 8): Uses digits 0-7
Common Use Cases
- Computer programming and low-level system operations
- Understanding memory addresses (typically in hexadecimal)
- Network configurations and IP addressing
- Color representation in web development (hexadecimal)
- Binary data analysis and manipulation
- Computer science education and algorithm development
How to Use
Enter a number in any of the input fields, and the tool will automatically convert it to all other number bases. The tool validates input based on the selected base.
