Formula
Acres = (length × width) ÷ 43,560.
When you enter square feet directly, acres = square feet ÷ 43,560. The result is shown to three decimal places. A tenth of an acre is 4,356 square feet.

Acreage calculator from feet or square feet
This acreage calculator divides square feet by 43,560. Enter the two sides of a rectangle, or enter square feet you already know. The acre is an exact unit. The measuring is the part that is approximate.

How it works
An acre is 43,560 square feet.
That figure is exact: a chain by a furlong, 66 by 660 feet, and also 208.71 feet on a side if the acre is square. Multiply length by width when you know both sides of a rectangle, then divide by 43,560. If a map or a previous measurement already gave you square feet, switch the input and divide that number. Square yards are square feet divided by 9. This does not account for slope. A steep field has more surface than its map acreage. Deeds and surveys control when they disagree with a wheel measurement.

Example
A field 250 feet by 400 feet.
The area is 100,000 square feet, which is 2.296 acres and about 11,111 square yards. Enter 43,560 in the square-feet mode and the result is 1.000 acre.

Tips
Rectangles only, unless you bring the area.
A pasture with a creek is not a rectangle. Use a survey or break the outline into shapes, add the square feet, and paste the total into the square-feet mode. GPS apps and deeds are better than a single wheel pass on a large tract.

Equipment
Acreage is how you size a tractor, not the loan.
A tractor or loader for the ground you measured can be an equipment request from $15,000 to $2 million. Dengaro arranges that financing. The acre figure is not a property value and not a payment.
Important questions
Know what to expect.
How many square feet are in an acre?+
43,560. The acreage calculator divides by that number and does not round it. Display rounding happens after the division.
What is a square acre in feet on each side?+
The square root of 43,560 is about 208.71 feet. A 208.71 by 208.71 foot square is one acre. Most fields are not square. Use the sides you measured.
Does slope change the acres?+
Map acreage is horizontal. The surface you mow or seed on a slope is larger. This page reports the horizontal area from the distances you enter.
Can I enter acres and get square feet?+
Enter the square feet, or enter a rectangle. To go from acres to square feet, multiply acres by 43,560. One acre typed as 43,560 square feet returns 1.000.
