How to convert 11101 to decimal, step by step
Give each bit its place value — 1, 2, 4, 8 and so on, doubling from the right — then add up the places where the bit is 1.
| Bit | Position | Place value | Bit × place |
|---|---|---|---|
| 1 | 4 | 16 | 16 |
| 1 | 3 | 8 | 8 |
| 1 | 2 | 4 | 4 |
| 0 | 1 | 2 | 0 |
| 1 | 0 | 1 | 1 |
Add the last column: 16 + 8 + 4 + 1 = 29. So 11101₂ = 29₁₀.
In short: 11101₂: 1×16 = 16 → +1×8 = 24 → +1×4 = 28 → +0×2 = 28 → +1×1 = 29
