There can be no conversion.
A linear foot is a measure of length in 1-dimensional space while a square foot is a measure of area in 2-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.
If you mean square feet, it really doesn't make sense to convert that.
1.73 metres = 5.68 feet (to 3 sf)
43,560 sf
2400 square feet.
This is a nonsense question. Tons of dirt can be converted to cubic feet, depending on moisture and dirt type, but not to sf or square feet.
12 acres = 522,720 square feet.
If you mean square feet, you can't convert from one to another. Those measurements, quite simply, measure different kinds of things.
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.
680 mm = 2.23 feet (to 3 sf). . . . . . 1 millimeter = 0.0032808399 feet
20' x 30' = 600. 600 sf.
1.99 acres is 86,684.4 square feet.
Tt depends on the amount of sod on the pallet. If it holds 50 yards, then 450 sf; if it 63 yards, then 567 sf.
