for convert hexadecimal to decimal, on RouterOS already exist this two methods (0x must be present):

:put 0xFF85

:put [:tonum "0xFF85"]

but this can be used (not only one byte):

:global hex2dec do={
    :local conv $1
    :if (!($conv~"^[0-9a-fA-F]+\$")) do={:return 0}
    :if ([:typeof [:find $conv "0x" -1]] = "nil") do={:set conv "0x$conv"}
    :return [:tonum $conv]
}

WARNING: RouterOS have a bug that do not recognize negative hex values, on future I mod the previous script to support QWORD hex conversion
