Covert from literal HEX value to INT MariaDB

All we need is an easy explanation of the problem, so here it is.

I have a situation where i need to get the integer value from a literal hex.
Example: "ff" equals 255 in decimal, but if i use the HEX("ff") function it returns 6666.
Is it possible to get it to return 255? Like a=10, b=11… and so on

Thank you
