About Octal to Decimal Conversion

This tool converts numbers from the Octal (Base-8) system to the standard Decimal (Base-10) system. The octal system uses digits from 0 to 7. To convert an octal number to decimal, each digit is multiplied by 8 raised to the power of its position (starting from 0 on the right). This tool automates that calculation, allowing you to quickly find the decimal equivalent of any octal number.
