How to Convert Binary to Decimal

Start from the right.
Multiply each digit by 2 raised to its position number (starting at 0), then add them all together.

---

Example: What is 11111111 in Decimal?

• 1 × 2⁷ = 128
• 1 × 2⁶ = 64
• 1 × 2⁵ = 32
• 1 × 2⁴ = 16
• 1 × 2³ = 8
• 1 × 2² = 4
• 1 × 2¹ = 2
• 1 × 2⁰ = 1

Add them up:

128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 = 255

11111111 in binary = 255 in decimal.
