You mean convert a numeric value that happens to be stored as an 8 bit value into the string representation of that number?

char strValue[4];
byte foo = 144;

sprintf(strValue, "%d", foo);

You don't want to convert a number into a "String" (that's String, not string - a String object as opposed to a C string) as the String object is the main cause of memory corruption and unexplained things happening on the Arduino.
