Octal is a numeral system that uses base 8, and as a result, has 8 symbols to represent numbers: 0-7. Octal notation is used in programming because it is a convenient way to express binary code. For example, the octal number "12" can be represented as "00010010" in binary. Octal conversion is simple: each digit in the octal number corresponds to 3 bits in the binary number. In other words, the value of each digit in octal is multiplied by 8^n, where n is the digit's position, starting from 0 on the right side. Octal conversion can be done manually or with an octal converter. To convert a text string into an octal, first determine the Unicode values of each character in the string. Then, convert each Unicode value into binary and concatenate all binary strings together. Finally, divide the concatenated string into groups of 3 bits and convert each group into its corresponding octal digit. The reverse process can be used to convert from octal back to text.
