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.
My father is a carpet installer so we used this all the time. One yard = 3 feet, so an area that is 3 feet by 3 feet would equal one square yard. Since that area contains 9 square feet, then 9 sf = 1 sq yd. To convert a room measurement, multiply the length x width to arrive at the square feet and then divide by 9 (since there are 9 sf in a square yard) to arrive at the square yards. 12 x 20 = 240 sf / 9 = 26.66 sq yds

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.)
