    Octal to decimal formula

    An octal number is a sum of powers of 8. Number the digits from the right starting at 0 and multiply each by 8 to the power of its position:

    value = dn×8n + … + d1×81 + d0×80

    Example: 755 = 7×82 + 5×81 + 5×80 = 448 + 40 + 5 = 493.

    Octal digits as 3 bits

    Each octal digit is exactly three bits, which is why octal is used for Unix permissions (read = 4, write = 2, execute = 1).

    Frequently asked questions

    How do you convert octal to decimal?

    Multiply each octal digit by 8 raised to its position, counting from 0 on the right, and add the results. For 755: 7×64 + 5×8 + 5×1 = 448 + 40 + 5 = 493.

    What is 777 in decimal?

    Octal 777 is 511: 7×64 + 7×8 + 7 = 448 + 56 + 7. It is also the Unix permission "rwxrwxrwx".

    Which digits can an octal number use?

    Only 0 to 7. An 8 or 9 means the number is not octal, and the converter shows an error.

    Where is octal used?

    Mostly for Unix and Linux file permissions (chmod 755, 644), in some older computers and in programming escape sequences such as \101 for "A".

    Does it accept the 0o prefix?

    Yes. Prefixes like 0o (Python, JavaScript) and spaces or underscores between digits are ignored.

    Can it convert huge octal numbers?

    Yes. It uses BigInt arithmetic, so any length converts exactly.
