How to convert 100000 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 | 5 | 32 | 32 |
| 0 | 4 | 16 | 0 |
| 0 | 3 | 8 | 0 |
| 0 | 2 | 4 | 0 |
| 0 | 1 | 2 | 0 |
| 0 | 0 | 1 | 0 |
Add the last column: 32 = 32. So 100000₂ = 32₁₀.
In short: 100000₂: 1×32 = 32 → +0×16 = 32 → +0×8 = 32 → +0×4 = 32 → +0×2 = 32 → +0×1 = 32
