It is not possible to convert feet to acres, because feet measure length and acres measure area. However, you can first find the number of rectangular square feet by multiplying length times width, then convert to acres by dividing the number of square feet by 43,560.
- Determine length and width of the area, if square footage is not known
If the number of square feet is not known, take the rectangular area and measure the length and width in feet. The direction of length and width should be perpendicular. If the area is not a perfect rectangle, break the area into smaller rectangles and record length and width measurements of each smaller rectangle individually.
- Determine the number of square feet you have
Find the total number of square feet you want to convert to acres. If you took length and width measurements, multiply the length and width in feet together to get the area of the rectangle in square feet. If you took multiple rectangular measurements, add the areas of the different rectangles together to get the total square footage.
- Divide the number of square feet by 43,560
Take the number of square feet and divide it by 43,560. It is equivalent to performing the operation (number of square feet) * (1 acre/43560 square feet). Be sure to express your result in terms of acres.
