How to convert 28A to octal
Step 1: Hexadecimal to decimal
Multiply each digit by 16 to the power of its position (0 on the right), then add:
| Digit | Place value | Digit × place |
|---|---|---|
2 | 162 = 256 | 512 |
8 | 161 = 16 | 128 |
A = 10 | 160 = 1 | 10 |
512 + 128 + 10 = 650
Step 2: Decimal to octal
Divide by 8 repeatedly and keep the remainders. Reading the remainders from the last one to the first gives the octal digits:
| Division | Quotient | Remainder (digit) |
|---|---|---|
| 650 ÷ 8 | 81 | 2 |
