P1kachu presents: How to Hexadecimal!

In this tutorial I will show you how to read and write in Hexadecimal language.

First you must know how to convert numbers to Hex.
Look at this pattern closely:

1 = 1
2 = 2
...
8 = 8
9 = 9
10 = A
11 = B
12 = C
13 = D
14 = E
15 = F
16 = 10
17 = 11
18 = 12

Have you noticed anything?

In hex, the number next to 9 goes to A, then continues up to F then becomes 10.
It's like in the decimal system, when it reaches 9 then it goes to 10.

Now, let's count up to 30 using hex:
1,2,3,4,5,6,7,8,9,A,B,C,D,E,F,
10,11,12,13,14,15,16,17,18,19,1A,1B,1C,1D,1E,1F,
20,21,22,23,24,25,26,27,28,29,2A,2B,2C,2D,2E,2F,30!

Next lesson is to learn how to convert hex to decimal.

It's actually pretty easy,
For example:

14 = 1×16¹ + 4×16⁰ = 20

Get it?
Another example:

69A = 6×16² + 9×16¹ + 10×16⁰ = 1690

So you understand now? I'll just assume you did ( ͡° ͜ʖ ͡°)

Next, decimal to hex.

It's easier...
Just express it in power of 16:

Ex.
69 = 4×16¹ + 5×16⁰ = 45

Another example:
61 = 3×16¹ + 13×16⁰ = 3D

Now for the hard part...
Converting letters to hex!

Just remember this:
Uppercase letters start with 4 or 5
Lowercase letters start with 6 or 7

Okay, now let's take for example, uppercase letter P.

First, get the position of the letter P in the alphabet, which is 16th...
Convert 16 to hex.
16 is 10 when converted to hex.

Now, add this number to 40. (Since uppercase letters start with 4)
40 + 10 = 50.

Therefore, uppercase letter P in hex is 50.

For lowercase, just do the same except that you add it to 60.
Therefore, 60 + 10 = 70.

Therefore, lowercase letter P in hex is 70.

Now, to get words, just combine the letters.
For example, Pikachu
P = 50
i = 69 ( ͡° ͜ʖ ͡°)
k = 6B
a = 61
c = 63
h = 68
u = 75

Just combine these number bits and we get:
50696B61636875

How about numbers?

Number always start with 3.

Therefore, to convert any ASCII number, you just add this number to 30.
For example,

"5" = 35
"69" = 3639

Lastly, to convert spaces, symbols, etc.

Just memorize this list, these are the most commonly used symbols:
Space = 20
Period = 2E
Question Mark = 3F
Exclamation Mark = 21
