About the Number Base Converter
Convert between binary, octal, decimal, and hexadecimal with the full working shown.
What it is
Computers, and the people who program them, frequently need to move between number bases โ binary for low-level logic, hex for memory addresses and color codes, octal for file permissions. This tool converts any value between binary, octal, decimal, and hexadecimal, live as you type, with the full working shown.
Features
Any-to-any conversion
Convert between binary, octal, decimal, and hexadecimal in either direction.
All 4 bases shown at once
A live table updates every representation simultaneously as you type.
Step-by-step working
Positional-weight expansion to decimal, and repeated-division steps to any other base.
Negative number support
Negative integers are handled and clearly labelled, not silently misread.
