How Binary to Octal Conversion Works

Binary uses the base-2 number system with only 0 and 1, while octal uses base-8 digits from 0 to 7. Since one octal digit represents exactly three binary bits, conversion can be done by grouping binary digits into sets of three.

Example: Convert binary 101101 to octal.

Binary Group Octal Digit
101 5
101 5

Therefore, binary 101101 equals octal 55.
