From Text to Base-16: Understanding HEX Encoding 🔡
Computers store all data as numbers. Character encoding systems like ASCII are the bridge that connects the text we read to the numbers a computer understands. This tool demonstrates this by converting text into the hexadecimal (base-16) number system, a compact and human-friendly way to represent the underlying data.
How the Conversion Works
The conversion from text to hexadecimal is a two-step process:
- Text to ASCII: The tool first takes each character in your input string and finds its corresponding decimal number from the ASCII table. For example, the letter 'H' is represented by the decimal number 72.
- Decimal to HEX: It then converts this decimal number into its hexadecimal (base-16) equivalent. The decimal number 72 is equal to the hexadecimal number 48.
Let's convert the word "Hi" as an example:
- 'H' → ASCII 72 → HEX 48
- 'i' → ASCII 105 → HEX 69
The final output is the sequence of these hexadecimal numbers, often separated by a space for clarity: 48 69. This is a common way to represent text data in programming and network analysis because it's more compact than binary but still directly related to how the data is stored.
