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.)
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.
To convert square feet (SF) to square yards (SY), you can use the formula: SY = SF ÷ 9. This is because one square yard is equal to 9 square feet. Simply divide the total square feet by 9 to obtain the area in square yards.
There are 92.903 square meters (SM) in one square foot (SF). To convert square feet to square meters, you can multiply the number of square feet by 0.092903. Conversely, to convert square meters to square feet, multiply by 10.7639.
One square foot (sf) is equivalent to approximately 0.092903 square meters (m²). To convert square feet to square meters, you can multiply the area in square feet by this conversion factor. Therefore, 1 sf is about 0.0929 qm (square meters).

square foot/feet
There are 92.903 square meters (SM) in one square foot (SF). To convert square feet to square meters, you can multiply the number of square feet by 0.092903. Conversely, to convert square meters to square feet, multiply by 10.7639.
One square foot (sf) is equivalent to approximately 0.092903 square meters (m²). To convert square feet to square meters, you can multiply the area in square feet by this conversion factor. Therefore, 1 sf is about 0.0929 qm (square meters).
To convert square feet (SF) to cubic yards (CY), you first need to convert square feet to cubic feet by multiplying the area in square feet by the thickness or height in feet. Then, divide the total cubic feet by 27, since there are 27 cubic feet in one cubic yard. The formula can be summarized as: CY = (SF × thickness in feet) ÷ 27.
400x1.6-6,400 sf
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
1.99 acres is 86,684.4 square feet.
2400 square feet.
