How to convert 1010001 to ternary
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 | 26 = 64 | 64 |
0 | 25 = 32 | 0 |
1 | 24 = 16 | 16 |
0 | 23 = 8 | 0 |
0 | 22 = 4 | 0 |
0 | 21 = 2 | 0 |
1 | 20 = 1 | 1 |
64 + 0 + 16 + 0 + 0 + 0 + 1 = 81
Step 2: Decimal to ternary
Divide by 3 repeatedly and keep the remainders. Reading the remainders from the last one to the first gives the ternary digits:
| Division | Quotient | Remainder (digit) |
