The Acreage Calculator helps you determine the size of a rectangular or square piece of land in acres, given its length and width in feet. Land measurement is crucial for various purposes, including real estate transactions, property development, agriculture, and even simple gardening planning.
How it Works: The Math Behind the Calculation
The calculation follows these simple steps:
Calculate Area in Square Feet: The area of a rectangle (or square) is found by multiplying its length by its width.
Area (sq ft) = Length (ft) × Width (ft)
Convert Square Feet to Acres: An acre is a unit of land area, and there are 43,560 square feet in one acre. To convert the total square feet to acres, we divide the area in square feet by 43,560.
Area (acres) = Area (sq ft) / 43,560
Common Use Cases
Real Estate: Buyers and sellers use acreage to understand property size, compare listings, and determine property value.
Agriculture: Farmers and ranchers need to know the acreage for planting crops, managing livestock, and applying fertilizers or pesticides.
Development: Developers use acreage to plan housing projects, commercial centers, and other land-use initiatives.
Landscaping and Gardening: Homeowners can calculate the size of their yard for landscaping projects, lawn care, or garden planning.
Boundary Surveys: Surveyors use these calculations as a fundamental step in defining property lines and areas.
This calculator assumes a perfectly rectangular or square plot of land. For irregularly shaped parcels, more complex surveying methods are required.

}
var squareFeet = length * width;
var acres = squareFeet / 43560;
// Format the output for better readability, especially for acres
resultDisplay.textContent = acres.toFixed(4); // Show 4 decimal places for acres
sqftDisplay.textContent = squareFeet.toLocaleString(); // Use locale formatting for square feet
