How to convert ASCII number into decimal number

Hello, I need help.
Let's say we have this code:
Code: Select all
mov si, number
call change_number
number db "80"
As you can see, the number is actually a number in ASCII text. How do I convert this to 80 itself (non ASCII)? I don't mind if you tell me to do it in hex or decimal, both are fine.
Help will be greatly appreciated!

I'd expect OS devers to be able to either figure out trivial things like this on their own or have sufficient google-fu skills.
What have you tried?

Pretty much everything, there's nothing on this topic anywhere.
Just if it may help, I'm doing this in NASM.
