So an airliner cruising at FL330 has 33,000 indicated on its altimeters (as at present). A pilot flying circuits in his Cub or Cessna 152 will report his flight level (not altitude) as (for example) 14 (or 014).

Except the difference between QNH and STD could be huge. Your Cessna could be flying at 200 ft above ground in your scenario.
