Octal to Binary

Octal to binary conversion is the process of converting an octal number, which is represented using base 8 digits (0–7), to its equivalent binary form.

To convert an octal number to binary, you can use the following method:

  1. Convert each octal digit to its equivalent binary form.
  2. Group the binary digits in groups of 3, starting from the rightmost digit.

For example, to convert the octal number 34 (binary: 110100): 3 -> 0011; 4 -> 0100; concatenate those two results together: 00110100 = 110100

A more simple way to convert octal to binary is to use a built-in function in most programming languages, like Python's bin() function which converts the octal number to binary by default or by using any web conversion tools like Oumify.

Bin(34) would return the binary value 110100, for example.

Another way is to use the built-in int() function and pass the octal number and the base 8 as arguments. In this case, int("34", 8) would return the binary value 110100.

Note that the binary representation uses only digits 0 and 1 to represent numbers.
