How to convert binary to senary
Go through decimal: first multiply each digit by 2 raised to the power of its position (counting from 0 on the right) and add the results; then divide the number by 6 again and again and write down the remainders; read in reverse order, the remainders are the senary digits.
Example: 11111111 to senary
Step 1: Binary to decimal
Multiply each digit by 2 to the power of its position (0 on the right), then add:
| Digit | Place value | Digit × place |
|---|---|---|
1 | 27 = 128 | 128 |
1 | 26 = 64 | 64 |
1 | 25 = 32 | 32 |
1 | 24 = 16 | 16 |
1 | 23 = 8 | 8 |
1 | 22 = 4 | 4 |
1 | 21 = 2 | 2 |
1 | 20 = 1 | 1 |
128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 = 255
Step 2: Decimal to senary
Divide by 6 repeatedly and keep the remainders. Reading the remainders from the last one to the first gives the senary digits:
| Division | Quotient | Remainder (digit) |
|---|---|---|
| 255 ÷ 6 | 42 | 3 |
| 42 ÷ 6 | 7 | 0 |
| 7 ÷ 6 | 1 | 1 |
| 1 ÷ 6 | 0 | 1 |
Result: 255 = 1103 in senary.
