What Is Hexadecimal?

The hexadecimal number system is a base-16 system that uses:

Numbers: 0–9
Letters: A–F

Hexadecimal is commonly used to represent binary data in a compact and human-readable form.

What Is ASCII?

ASCII (American Standard Code for Information Interchange) is a character-encoding standard that assigns numeric values to:

Letters (A–Z, a–z)
Numbers (0–9)
Symbols and punctuation
Control characters

Each ASCII character is represented by a decimal or hexadecimal value.

How Hex to ASCII Conversion Works

The core rule is simple:

Each ASCII character is represented by one byte (2 hex digits).

Example Breakdown

Hex: 48
Decimal: 72
ASCII: H
