Formula

Each character is converted using its ASCII code value.

Binary: code = charCodeAt(i); binary = code.toString(2).padStart(8,'0')
Hex: hex = code.toString(16).toUpperCase().padStart(2,'0')
Octal: octal = code.toString(8).padStart(3,'0')
Decimal: decimal = String(code)

Example

Input: A (ASCII 65)
Binary: 01000001
Hex: 41
Octal: 101
Decimal: 65
