One octal digit corresponds exactly to three binary digits.
To convert from octal to binary:
Simply replace each octal digit with three binary digits.
Group digits in fours from the right for easy reading.
Example: Convert the octal number 270618 to binary.
270618 = 010 111 000 110 0012
= 0010 1110 0011 00012
This can also be used in reverse.
Regroup in threes from the right then use the table.
Example: Convert the binary number 1001 0101 10002 to octal.
1001 0101 10002
= 100 101 011 0002
= 45308 in octal.
