📖 About String to ASCII Converter
What is ASCII?
ASCII (American Standard Code for Information Interchange) is a character encoding standard that assigns numeric values to letters, numbers, punctuation marks, and control characters. Each character is represented by a number between 0 and 127.
How ASCII Encoding Works
In ASCII, each character is mapped to a unique numeric value. For example:
- 'A' = 65 (decimal) = 41 (hex) = 101 (octal) = 01000001 (binary)
- 'a' = 97 (decimal) = 61 (hex) = 141 (octal) = 01100001 (binary)
- '0' = 48 (decimal) = 30 (hex) = 60 (octal) = 00110000 (binary)
Common Use Cases
- Programming: Understanding character encoding for string manipulation
- Debugging: Identifying hidden characters in text files
- Data Processing: Converting between text and numeric representations
- Network Protocols: Working with text-based protocols that use ASCII
- Education: Learning about character encoding systems
