Number Base Converter

The Number Base Converter is a simple yet powerful tool for converting numbers between different numeral systems. It supports the four most common bases used in computing and mathematics.

Supported Bases

Decimal (Base 10): The standard system for denoting integer and non-integer numbers. It uses digits from 0 to 9.
Binary (Base 2): The foundation of all modern computing systems. It uses only two digits: 0 and 1.
Hexadecimal (Base 16): Widely used in computer science to represent binary values in a more human-readable form. It uses digits 0-9 and letters A-F.
Octal (Base 8): Uses digits from 0 to 7. While less common today, it is still used in some computing contexts like file permissions in Unix/Linux.

How to use

Simply type a number into any of the input fields. The tool will automatically convert that number into all other supported bases in real-time.

Examples

Common pitfalls

!
Invalid Input: Ensure input is a valid number in the selected base. Avoid using invalid characters.
!
Base Mismatch: Verify that the input and output bases are correctly selected to avoid incorrect conversions.
!
Overflow Error: Be aware of potential overflow errors when converting large numbers between bases.
!
Rounding Errors: Note that some conversions may result in rounding errors due to the inherent properties of the number bases.
