Convert octal code to binary, decimal, and hex simultaneously.
Enter an octal number (digits 0-7) and instantly see its binary, decimal, and hexadecimal equivalents. Because each octal digit maps to exactly three binary digits, octal is a compact way to express binary values - the tool handles the grouping automatically.
The best-known use of octal is Linux and Unix file permissions: chmod 755 or 644 are octal numbers describing read, write, and execute rights for owner, group, and others. Computer science students also use octal conversions when learning number systems, and this converter removes the manual math from the process.
