How to Use This Calculator
  1. Enter the Decimal value you want to convert (e.g., 255 equals 0xFF in hex).
  2. Read the Hexadecimal output with and without the 0x prefix — copy directly into code.
  3. Check the Binary output for bit-level inspection of the same value.
  4. Use the 8-bit padded Binary form when working with byte-aligned data structures.
  5. The Octal result is useful for Unix file permission modes and legacy system work.
