Octal to ASCII Converter
This tool allows you to convert between octal (base-8) values and ASCII text characters.
How to Use This Converter
- Enter an octal value like
110 145 154 154 157to get ASCII text (e.g., "Hello") - Or enter ASCII text to see its octal representation
Understanding the Conversion
Each ASCII character has a unique numeric value. Octal is one way of representing that value, especially in low-level systems like UNIX.
Example: The word "Hello" in octal:
| Character | ASCII (Decimal) | Octal |
|---|---|---|
| H | 72 | 110 |
| e | 101 | 145 |
| l | 108 | 154 |
| l | 108 | 154 |
| o | 111 | 157 |
Result: 110 145 154 154 157 → "Hello"
Why Use Octal?
Octal representation is still relevant in contexts such as:
- UNIX file permissions (e.g.,
chmod 755) - Working with ASCII in legacy systems
- Viewing octal values in raw data formats
