How to convert 1001001 to vigesimal
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 |
0 | 24 = 16 | 0 |
1 | 23 = 8 | 8 |
0 | 22 = 4 | 0 |
0 | 21 = 2 | 0 |
1 | 20 = 1 | 1 |
64 + 0 + 0 + 8 + 0 + 0 + 1 = 73
Step 2: Decimal to vigesimal
Divide by 20 repeatedly and keep the remainders. Reading the remainders from the last one to the first gives the vigesimal digits:
| Division | Quotient | Remainder (digit) |
|---|---|---|
| 73 ÷ 20 | 3 | D (13) |
| 3 ÷ 20 | 0 | 3 |
