1 foot is 12 inches, therefore 1 square foot is (12 x 12) = 144 square inches. To determine the number of square feet, divide the number of square inches by 144 (the number of square inches in a square foot). 1800 / 144 = 12.5 square feet.
You can't convert that. You can convert feet to inches, or square feet to square inches.
30 feet by 28 feet equals 840 square feet. 30 inches by 28 inches equals 840 square inches, or 5.833 square feet.
