2. Click “Convert”
   Press the Convert button to start the conversion. A short progress animation appears while the tool processes your input.
3. View the Results
   After a few seconds, the calculator displays:
   • The original binary number
   • The equivalent decimal value
   • A step-by-step explanation showing how each binary digit contributes to the final decimal total.
4. Copy or Share the Results
   Use the “Copy Results” button to copy the conversion output or click “Share Results” to post it on social media or send it to others.
5. Reset and Try Again
   Click the “Reset” button to clear all inputs and start a new conversion instantly.

💡 Practical Example

Let’s say you want to convert the binary number 10110101 into decimal.

Here’s how it works:

• Binary Input: 10110101
• Step-by-step calculation: 1×2^7 + 0×2^6 + 1×2^5 + 1×2^4 + 0×2^3 + 1×2^2 + 0×2^1 + 1×2^0 = 128 + 0 + 32 + 16 + 0 + 4 + 0 + 1 = 181
• Decimal Output: 181

The calculator automatically performs all these steps and displays the process clearly for easy learning and verification.
