Octal to Decimal Converter

How It Works

Octal (base-8) uses digits 0-7. Each position represents a power of 8:

  • Digit 0: 8^0 = 1
  • Digit 1: 8^1 = 8
  • Digit 2: 8^2 = 64
  • Digit 3: 8^3 = 512
  • Digit 4: 8^4 = 4096
  • Digit 5: 8^5 = 32768
  • Multiply each digit by its place value and sum all the results.
