Binary to Decimal

What is the Binary to Decimal Converter?

This tool converts binary numbers (base-2) to decimal numbers (base-10), helping you understand how computers represent data.

Why Convert Binary to Decimal?

Binary conversion is essential when:

• Learning programming — understanding how data is stored
• Debugging code — reading memory addresses and flags
• Network configuration — subnet masks use binary
• Digital electronics — working with logic circuits

The Conversion

Each binary digit represents a power of 2, from right to left: 1, 2, 4, 8, 16, 32...

For example: 1010 = 1×8 + 0×4 + 1×2 + 0×1 = 10

How to Use

1. Enter binary number — type digits using only 0 and 1
2. View decimal result — the conversion appears instantly
3. Copy the result — use in your code or calculations

Common Binary Values

• 1111 = 15 (4-bit max)
• 11111111 = 255 (8-bit/byte max)
• 1111111111111111 = 65,535 (16-bit max)
