Our Acreage calculator helps you estimate the size of an area by taking into account its width and length. It facilitates conversions between various area units. Feel free to choose your preferred measurement system, provide the length and width inputs, and the calculator will instantly display the corresponding acreage.
Acreage and Area Calculator
Enter the length and width of the land plot to calculate the acreage and area in various units:
If you know the square footage, square mileage, square yards, square meters, or hectares of the area, you can use the formulas below to calculate area to acreage.
Acres = square feet ÷ 43,560
Acres = square miles x 640
Acres = square yards ÷ 4,480
Acres = square meters ÷ 4,046.86
Acres = hectares x 2.471

How to Calculate the Acreage of an Irregular Lot
Calculating the acreage of a perfect square or rectangle is simple – multiply the length by the width in your preferred unit to find the area. Then convert that to acreage. But, the steps are more complicated when you have an irregular lot.
One option is to break your irregular plot of land into easy-to-measure rectangles, find the area of each, and add them all together before converting to acreage. For example, if your plot of land is an “L” shape, you can break it into two rectangles, find the square footage of each, add them together, and then divide by 43,560 to determine the number of acres.
But if your plot is irregular, digital mapping software is a more accurate method to determine acreage. Some of these programs will allow you to outline a property on Google maps and convert it to an approximate amount of acreage.
A professional land survey is the most accurate (but more expensive) way to determine acreage of irregular lots.
How to Measure the Acreage of a Triangle
To measure the acreage of a triangle, you’ll need to know the base and height in your preferred unit of measurement. Then use this formula to determine the area: 0.5 x base x height. After figuring out the area, convert it to acreage.
Here’s an example of measuring the acreage of a triangle. We’ll use feet and square feet as our preferred measurement form.
Our triangle has a base (the longest part of the triangle) of 500 feet and a height of 300 feet. So, we’ll use the following formula to find the square footage.
Square feet = 0.5 x 500 x 300
75,000 = 0.5 x 500 x300
To determine our acreage, we’ll divide our square footage by 43,560.
Acreages = 75,000 ÷ 43,560
1.722 = 75,000 ÷ 43,560
Our triangle contains 1.722 acres.
Frequently Asked Questions (FAQ)FAQ
How do you calculate acreage with feet?
To calculate acreage with feet, measure your area and multiply width x length to determine square feet. Then, divide the square footage by 43,560 to determine acreage.
How many acres are in a mile?
Since a mile measures length and an acre measures area, you can’t measure them against each other. However, you can measure a square mile against an acre, and there are 640 acres in one square mile.
What is the length and width of an acre?
There’s no set length and width of an acre. An acre can be any shape if its area adds up to 43,560 square feet or 4,047 square meters.
How to tell how many acres my property is?
If you live in the United States, you can access your county auditor or local tax assessor’s website to look at public land records, including property values and lot sizes.
How many square feet is .23 acres?
If you have .23 acres, it’s the equivalent of 10,018.8 square feet.
To calculate the acreage, the length and width of the land, which is usually given in feet, is multiplied to get the area in square feet. Then, this area in square feet is converted to acres by using the conversion factor of 43560.
Explanation. One acre is defined as 43,560 square feet. This means there are 43,560 sq ft per acre. To convert square feet to acreage just divide the number of square feet by 43,560.
A parcel of land that is 330 feet by 330 feet contains approximately 2.5 acres, calculated by multiplying the dimensions to get the area in square feet and then dividing by the conversion factor to acres.
and so forth. You can also easily calculate the acreage of your land by giving the square feet. You will take your land square feet and divide it by 43,560. For example, if you have a piece of land that is 550,000 square feet, you will divide it by 43,560, which equals 12/6 acres.
200 feet x 200 feet = 0.918 acres. Or in other words, approximately 92% of an acre. An Acre is approximately equal to a square that measures 208.71 feet on each side, which is the √43560.
Answer and Explanation: One acre is equal to 43,560 square feet, which means that a quarter acre is equal to: 43 , 560 4 = 10 , 890 s q u a r e f e e t .
How is land area calculated? The area of a piece of land can be calculated in any unit. The length and breadth of the land is measured at first and the results are multiplied. The product of the length and breadth of the land is the area of the land.
To calculate the number of acres in a parcel of land, divide the area of the land in square feet by the number of square feet in an acre (43,560). In this case, a parcel of land measuring 660' by 660' contains 10 acres.
To calculate acres by hand, multiply your length and width (in feet) to get square feet.Try our length converter if needed.Then divide by 43,560 to determine the size of the land in acres.
Multiply the length (feet) and width (feet) of land to get the area in square feet.Then, convert the area into acres by using the conversion factor of 43560. Divide the area by the conversion factor because 1 acre = 43,560 square feet.
Enter an address or zoom into the map then click on the starting point of your shape. Continue to click along the outside edge of the shape you want to calculate the area of. As you add points the area will be updated below and converted into acres, square feet, meter, kilometers and miles.
200 feet x 200 feet = 0.918 acres. Or in other words, approximately 92% of an acre. An Acre is approximately equal to a square that measures 208.71 feet on each side, which is the √43560.
Divide the square footage of the enclosed area by 43560. This will give you the number of acres. The accuracy of the number is dependent on how good of a job you did in taking field dimensions and in laying out those dimensions.
