Example Conversions

Example 1: Binary to Decimal

Input: 1101
Output:

  • Decimal: 13
  • Hexadecimal: D
  • Octal: 15

Steps:

  • 1 × 2^0 = 1
  • 0 × 2^1 = 0
  • 1 × 2^2 = 4
  • 1 × 2^3 = 8
  • Sum = 13

Example 2: Decimal to Binary

Input: 25
Output:

  • Binary: 11001
  • Hexadecimal: 19
  • Octal: 31

Steps:

  • 25 ÷ 2 = 12 remainder 1
  • 12 ÷ 2 = 6 remainder 0
  • 6 ÷ 2 = 3 remainder 0
  • 3 ÷ 2 = 1 remainder 1
  • 1 ÷ 2 = 0 remainder 1
  • Read remainders bottom to top → 11001
