How to convert 1011010 to quaternary
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 |
1 | 23 = 8 | 8 |
0 | 22 = 4 | 0 |
1 | 21 = 2 | 2 |
0 | 20 = 1 | 0 |
64 + 0 + 16 + 8 + 0 + 2 + 0 = 90
