Acreage Calculation Formula:
From: | To: |
This calculation estimates the acreage of a circular area based on its perimeter measurement. It assumes the perimeter forms a perfect circle to approximate the enclosed area.
The calculator uses the formula:
Where:
Explanation: The formula derives from calculating the area of a circle from its circumference, then converting from square feet to acres.
Details: Estimating acreage from perimeter is useful for land measurement, agricultural planning, and property assessment when only boundary measurements are available.
Tips: Enter the perimeter measurement in feet. The value must be greater than zero for valid results.
Q1: How accurate is this calculation?
A: It's an approximation that assumes a perfect circular shape. Actual acreage may vary for irregular shapes.
Q2: What's the conversion factor for acres?
A: 1 acre equals 43,560 square feet.
Q3: Can I use this for rectangular areas?
A: For rectangles, use (length × width)/43560 for more accurate results.
Q4: What's the minimum perimeter I can enter?
A: Any positive value greater than zero, but very small values will give tiny acreage results.
Q5: How does perimeter relate to acreage?
A: For a given perimeter, a circular shape encloses the maximum possible area.
