How to Convert Binary to Octal Number

Steps

1 Consider any binary number. A binary number consists of only 0's and 1's.

2 Group all the bits in the binary number, as a set of 3 bits. Start from the right: approaching from least significant bit to the most significant bit.

• If any bit remains ungrouped in a set of 3 bits then you can add a leading '0' to it on the left, to make it a perfect set.

3 Find the octal numbers and their equivalent binary numbers, as given in the picture. 

4 Replace each 3-bit binary number set to its equivalent octal number.

5

Hence the number obtained after replacing is the equivalent octal number.
