| To convert square footage to acreage | Divide the number of square feet by 43, 560 |
| To convert acreage to square feet | Multiply the number of acres by 43, 560 |
| If you are given the dimension only (300x200) the first number is considered to be | Front footage |
| A parcel of land measures 400x400 (sq.) how many acres are contained in this parcel? | 400x400 = 160,000 square feet 160,000 sq ft / 43, 560 = 3.6731 Acres |
| A parcel of land is 7.5 acres. How many square feet are in the parcel? | 43, 560 X 7.5 = 326, 700 sq. ft. |
