What is Hexadecimal?

Hexadecimal is a number system that uses sixteen digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F. It is also known as base 16 numbering system since it is based on 16 following symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E and F.

How to convert ASCII to Hexadecimal?

To convert ASCII to Hexadecimal, we need to convert each character to it's ASCII value, then convert that ASCII value to Hexadecimal.

Example

Let's convert the word "Hello" to Hexadecimal.

First, we need to convert each character to it's ASCII value.

Character	ASCII Value
H	72
e	101
l	108
l	108
o	111

Now, we need to convert each ASCII value to Hexadecimal.

ASCII Value	Hexadecimal Value
72	48
101	65
108	6C
108	6C
111	6F

Finally, we need to combine all the Hexadecimal values together to get the final Hexadecimal value. In this case, the final Hexadecimal value is 48 65 6C 6C 6F. This is the Hexadecimal representation of the word "Hello".
