Convert a number between binary, octal, decimal, and hexadecimal — see all four representations at once from any input base.
How it works
- Enter a number into any of the base fields (Decimal, Hex, Binary, Octal).
- The engine parses the integer and instantaneously translates it.
- Read the synchronized outputs across all other numeric bases.
Frequently asked questions
Why is hexadecimal used so commonly in programming?
Each Hex digit maps perfectly to four binary bits. It acts as a compact, highly readable shorthand for binary memory addresses and color codes.
What is octal actually used for today?
While historically vital, it survives today predominantly in Unix and Linux file permission schemes (e.g., chmod 755).
Can the calculator handle decimal fractions?
This specific tool handles integers. Fractional base conversion requires floating-point math.
