The abbreviation is (sq. ft.) I do believe.
I will assume that sf is square foot. 1 yard is 3 feet long, one square yard is 3x3 or 9 square feet. Therefore 100,000 square feet divided by 9: 100,000 / 9 = 11111 yards and one square foot
70,132 square feet = 1.61 acres
One acre is 43,560 square feet or 4840 square yards. The conversion would be 1.4 acres.
900 square meters are 9687.519375 square feet.
To convert square yards to square feet, you can multiply the number of square yards by 9, as there are 9 square feet in 1 square yard. So, if you have 5 square yards, you would have 45 square feet (5 x 9).
square foot/feet
There are 9 square feet (sf) in a square yard (sy). This is because a square yard is defined as a square with each side measuring 3 feet, and when you calculate the area (3 feet x 3 feet), you get 9 square feet.
400x1.6-6,400 sf
YES ... I've seen both sf and sqft. Rule of thumb might be, "If your reader understands what you've written, it's a valid abbreviation." (I know the purists are going to beat me up for that, but that's the way I see it.)
1,432 square feet is 133.04 square meters.
I will assume that sf is square foot. 1 yard is 3 feet long, one square yard is 3x3 or 9 square feet. Therefore 100,000 square feet divided by 9: 100,000 / 9 = 11111 yards and one square foot
