How to convert 0011 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 |
|---|---|---|---|
| 0 | 3 | 8 | 0 |
| 0 | 2 | 4 | 0 |
| 1 | 1 | 2 | 2 |
| 1 | 0 | 1 | 1 |
Add the last column: 2 + 1 = 3. So 0011₂ = 3₁₀.
In short: 0011₂: 0×8 = 0 → +0×4 = 0 → +1×2 = 2 → +1×1 = 3
Frequently asked questions
How do you convert 0011 to decimal?
Use place values. The 1 bits sit at place values 2, 1, and 2 + 1 = 3. So 0011₂ = 3₁₀.
Why does 0011 start with a 0?
The leading 0 adds nothing — its place value contributes 0 — so 0011 has the same value as 11: 3 in decimal. The extra zero just keeps the number at 4 bits wide, the way it is often written in code or in search queries.
