📘 How Binary to Decimal Conversion Works (Step-by-Step)

Let’s convert 1101 to decimal:

Binary1101
Power of 22³=82²=42¹=22⁰=1
Value8401

Add: 8 + 4 + 0 + 1 = 13

✅ So, 1101₂ = 13₁₀

Our binary decimal converter does this — instantly — for numbers up to 32 bits.


📚 Decimal to Binary: How It Works

Convert 27 to binary:

  1. Divide by 2 and track remainders:
    • 27 ÷ 2 = 13 rem 1
    • 13 ÷ 2 = 6 rem 1
    • 6 ÷ 2 = 3 rem 0
    • 3 ÷ 2 = 1 rem 1
    • 1 ÷ 2 = 0 rem 1
  2. Read remainders bottom to top: 11011

✅ So, 27₁₀ = 11011

Our tool automates this — no long division needed.
