ASCII to Hex Conversion
The ASCII to hexadecimal converter allows you to convert ASCII text into hex values, and vice versa.
How to Use This Converter
- Enter ASCII characters to convert them into hexadecimal format
- Or enter hexadecimal values to convert them back into ASCII text
This converter supports both directions: ASCII to hex and hex to ASCII.
Understanding the Conversion
Each ASCII character corresponds to a numeric value, which can be represented in hexadecimal (base-16). You can find these mappings in our ASCII table.
For example, the character "A" corresponds to the decimal value 65, which is 41 in hexadecimal.
Hex is commonly used in programming and digital electronics because it's a compact representation of binary data.
Example
Converting the text "Hello" to hexadecimal.
| Letter | Decimal | Hexadecimal |
|---|---|---|
| H | 72 | 48 |
| e | 101 | 65 |
| l | 108 | 6C |
| l | 108 | 6C |
| o | 111 | 6F |
More About ASCII
ASCII (American Standard Code for Information Interchange) maps characters to numeric values. These values are often represented in hexadecimal when working with low-level systems, debugging tools, or data encodings.
While ASCII itself uses 7-bit values, hexadecimal makes it easier to visualize and group binary data—especially in formats like UTF-8, network protocols, or hexadecimal dumps.
