About Octal to Binary Conversion

This tool converts numbers from the Octal (Base-8) system to the Binary (Base-2) system. This conversion is straightforward and common in computer science because of the direct relationship between the two bases. Each octal digit corresponds to exactly three binary digits (e.g., octal `7` is binary `111`). This tool automates the process, allowing for fast and accurate conversion of any octal number to its binary form.
