A relativly simple cypher that simply replaces english characters with numbers.

A: 1
B: 2
C: 3
D: 4
E: 5
F: 6
G: 7
H: 8
I: 9
J: 10
K: 11
L: 12
M: 13
N: 14
O: 15
P: 16
Q: 17
R: 18
S: 19
T: 20
U: 21
V: 22
W: 23
X: 24
Y: 25
z: 26

Hints with use:
I suggest using additional encryptions with this, as it is a simple cypher and it very easy to decode.

26 = Z &/or BF?

Most common ciphers you'll find on the forums are vigenere ciphers

I suppose Z could equal BF. That could add an extra layer of encryption.

Letters larger than I could be represented by two letters.

I = 1
V = 5
X = 10
L = 50
C = 100
M = 1000

The more variables the better.

You mean roman numerals?

You can also shift the numbers so that its more like
Z=1
A=2
B=3
C=4

That would be Skip 1. Its best to do a skip 1-13 if you're doing a skip, that way it wouldn't be any easier to just decode it using the alphabet backwards.

You can also Add 1
A=2
B=3
C=4
D=5
E=6
etc
Z=27

In this case I'd suggest a higher number, that isnt rounded.

But perhaps my personal favorite is Multiply #. I hope this is self explanatory.
Substitute # for a number.

Skip is one of my favorite ciphers, but I always prefer my homemade ones.
