    •Formula Used

    • –Octal to Decimal: Multiply each digit by 8 raised to the power of its position index (from right to left).
      Example: (345)8 = 3×8² + 4×8¹ + 5×8⁰ = 229
    • –Decimal to Octal: Divide the decimal number by 8 repeatedly and collect the remainders in reverse order.
      Example: (229)10 = (345)8
    • –Octal to Binary: Convert each Octal digit to its 3-bit Binary equivalent.
      Example: (345)8 = (011100101)2
