14 acres is 609,840 ft². The exact arithmetic is 14 × 43,560 = 609,840 square feet, using the defined factor rather than a rounded one, so this matches what a calibrated instrument would give you.
14 acres is 56,656 m², a square 238 m on a side. For comparison a full-size football pitch is a little over 1.7 acres, and a US residential lot is commonly a quarter of one.
The result sits 10 ft² short of 609,850 ft², so if you need a round figure to quote, 609,850 ft² is the honest nearest one. Plenty of people do this in their head: multiply by 44,000 instead of using the exact factor 43,560. At 14 that shortcut gives 616,000 square feet, off by 6160 square feet or about 1.01%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
