To convert acres to square feet, use the exact U.S. relation: 1 acre = 43,560 square feet.
Multiply the acreage by 43,560 to get ft2 - divide by 43,560 to go back to acres.
For mapping or real-estate work, retain appropriate significant figures and round at the end. Tip: if you know dimensions in yards first, remember 1 yd2 = 9 ft2, so acres × 4,840 × 9 also yields 43,560. For fractional areas, multiply the fraction by 43,560; e.g., 1/8 acre = 5,445 ft2.
Exactly 43,560 square feet. This is the standard U.S. customary relation used in surveying, real estate, and land planning.
Use: square feet = acres × 43,560. Example: 2.3 acres × 43,560 = 100,188 ft2. Multiply acreage by 43,560 and round to appropriate significant figures.
Use: acres = square feet ÷ 43,560. Examples: 21,780 ft2 = 0.5 acre; 10,890 ft2 = 0.25 acre; 65,340 ft2 ÷ 43,560 ≈ 1.5 acres.
