Über Number Base Converter

This number base converter translates between binary (base 2), octal (base 8), decimal (base 10), and hexadecimal (base 16). Enter a number in any base and see the converted values in all four bases simultaneously. Uses BigInt for arbitrary-precision arithmetic, so it handles numbers of any size without overflow. Binary output is grouped in nibbles (4-bit groups) for readability. Useful for programming, computer science, digital electronics, and working with memory addresses.

Häufig gestellte Fragen

How do I convert binary to decimal?
Select 'Binary (base 2)' as the input type, then enter your binary number (e.g., 10110011). The decimal value and all other bases appear instantly below.
What is the largest number this supports?
There is no practical limit. The converter uses JavaScript's BigInt type, which supports arbitrary-precision integers. You can convert numbers with hundreds of digits.
Why is binary grouped in 4-digit blocks?
Each group of 4 binary digits (a nibble) corresponds to one hexadecimal digit. This grouping makes it easier to mentally convert between binary and hex, and to identify byte boundaries.
