What is ASCII to Hex Conversion?
ASCII to Hex conversion transforms human-readable text into its hexadecimal (base-16) representation. Each character in ASCII has a corresponding numeric value, which can be expressed in hexadecimal format using digits 0-9 and letters A-F.
How Does It Work?
Every character you type on a keyboard has an ASCII code - a number between 0 and 127. When converting to hexadecimal:
- 'A' = ASCII 65 = Hex 41
- 'a' = ASCII 97 = Hex 61
- '0' = ASCII 48 = Hex 30
- Space = ASCII 32 = Hex 20
Example Conversion
| Text | Hex (with spaces) | Hex (no spaces) |
|---|---|---|
| Hello | 48 65 6C 6C 6F | 48656C6C6F |
| World | 57 6F 72 6C 64 | 576F726C64 |
