Q1: Why 43,560 square feet in an acre?
A: This is the historical definition of an acre, originally the amount of land tillable by one ox in one day.
Q2: Can I use this for irregular shapes?
A: No, this formula only works for rectangular areas. For irregular shapes, you'd need to break them into rectangles or use other methods.
Q3: How precise is this calculation?
A: The calculation is mathematically precise, but real-world accuracy depends on your measurement precision.
Q4: What's the difference between acres and hectares?
A: One hectare equals 2.471 acres. Hectares are part of the metric system, while acres are used in imperial/US customary systems.
Q5: Can I calculate acres from other units?
A: Yes, but you'd need to first convert your measurements to feet or convert the conversion factor (e.g., 1 acre = 4,840 square yards).
