The area calculator converts acres, square miles, square footage, square yardage, hectacres and square meters of a given area. This calculator is also perfect as a land calculator because it converts acres into square feet or square yards, etc.
To use this calculator, change the default value of any of the fields and recalculate the other fields by clicking on the button to the right of the field that you changed.
This calculator assumes that you have already calculated the actual area of a given space, whether it be acres, square feet or square yards, etc.
For instance, if you are trying to figure out how many square feet are in 2 acres, you can change the default value from 1 acre to 2 and click the button next to acres to calculate the values in the other fields. In this case, the result for Square Feet would be 87120.
If you know how many square feet are in a given area, you can enter that value in the Square Feet field and click the button next to it to calculate the other fields. Enter 100000 square feet in the Square Feet field and click the button next to it to calculate the other fields. Square yards will be 11111.11.
Enter a value of 1 in the Square Mile field and click the button next to it. 1 square mile equals 640 acres, or 27878400 square feet, or 3097600 square yards.
