How to convert 010 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 | 2 | 4 | 0 |
| 1 | 1 | 2 | 2 |
| 0 | 0 | 1 | 0 |
Add the last column: 2 = 2. So 010₂ = 2₁₀.
In short: 010₂: 0×4 = 0 → +1×2 = 2 → +0×1 = 2
Frequently asked questions
How do you convert 010 to decimal?
Use place values. The only 1 bit sits at place value 2, so the total is 2. So 010₂ = 2₁₀.
Why does 010 start with a 0?
The leading 0 adds nothing — its place value contributes 0 — so 010 has the same value as 10: 2 in decimal. The extra zero just keeps the number at 3 bits wide, the way it is often written in code or in search queries.
