The acre calculation by perimeter estimates land area in acres based on the perimeter measurement, assuming a square or rectangular shape. One acre equals 43,560 square feet.
The calculator uses the formula:
Where:
Note: This calculation assumes a perfect square shape unless additional dimensions are provided.
Details: Acre calculation is essential for land measurement, real estate, agriculture, and construction planning.
Tips: Enter the perimeter in feet. For rectangles, you may need to calculate separately using length and width measurements.
Q1: How accurate is perimeter-based acre calculation?
A: For perfect squares, it's very accurate. For rectangles, you need the length-width ratio. Irregular shapes require more complex methods.
Q2: What's the difference between acre and hectare?
A: 1 acre = 0.4047 hectares. Hectares are metric units used internationally.
Q3: Can I use this for circular plots?
A: No, circles require different formulas using radius or diameter.
Q4: Why 43,560 square feet in an acre?
A: Historically, it was the amount of land a yoke of oxen could plow in one day.
Q5: How to measure perimeter accurately?
A: Use surveying equipment, GPS devices, or professional land measurement tools for best accuracy.
