Steps
● Step 1 – Convert each octal digit to a 3 digit binary number (the octal digits may be treated as decimal for this conversion).
● Step 2 – Combine all the resulting binary groups (of 3 digits each) into a single binary number.
Example
Octal Number : 258
Calculating Binary Equivalent:
| Step | Octal Number | Binary Number |
| Step 1 | 258 | 210 510 |
| Step 2 | 258 | 0102 1012 |
| Step 3 | 258 | 0101012 |
Octal Number : 258 = Binary Number : 101012
