QUESTIONS

Square feet to acres converter questions

How do I convert square feet to acres?

Divide by 43,560. So 21,780 sq ft is 0.5 acres, 10,890 sq ft is 0.25 acres, and 43,560 sq ft is exactly one acre.

How many decimals should I publish?

Two for marketing copy, three on a lot table where small lots sit next to each other and buyers sort by size. Round every lot the same way so the table stays honest.

Why does the plat show a different acreage?

A recorded plat states the surveyed area, which follows the true boundary including curves and jogs. A frontage × depth estimate treats the lot as a rectangle and will be off by a few percent.

What about square meters and hectares?

One acre is 4,046.86 square meters, or 0.4047 hectares. One square foot is 0.0929 square meters. US plats and deeds use acres and square feet.
