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.
