How to Convert Binary to Decimal
Each binary digit represents a power of 2. Starting from the right, multiply each digit by 2⁰, 2¹, 2², and so on, then add the results.
Example: Convert 11010 to decimal
1 × 2⁴ = 16
1 × 2³ = 8
0 × 2² = 0
1 × 2¹ = 2
0 × 2⁰ = 0
Add the values → 16 + 8 + 0 + 2 + 0 = 26
Therefore, 11010₂ = 26₁₀.
