Specific weight is the weight of the material per unit volume. Water has the specific weight of 62.43 pounds per cubic foot or 9.807 Newtons per cubic meter.
One cubic foot of water is 7.4805 gallons.
There are 7.48052 US gallons per cubic foot.
One inch of rain over one square foot is 1/12 cubic foot of water. A cubic foot of water weighs about 62.4 pounds. 1/12 of that is about 5.2 pounds.

The weight of one square foot of water is zero pounds. A square foot is a measurement of area, not volume. Since a square foot has no height, it is not possible to fit even a single hydrogen atom inside a square foot. The weight of a cubic foot of water (a cube with each side equal to one foot) is about 62.42 pounds. The reason that I saw "about" is because the density of water changes according to its temperature, so that a cubic foot of water at 32 degrees Fahrenheit will weigh 62.42 pounds, but at 212 degrees Fahrenheit a cubic foot of water weighs 59.83 pounds.

I have not a firm answer. Compost weight is variable and as such the answer may be misleading. Consider this, a cubic foot of water weighs 64 pounds. A tonne is 1,000 kg. The number of cubic feet in a cubic yare is 27. so a cubic yard of water weighs 1,728 lb. A tonne is then 3,806.167 lb. of water. Now compost is lighter than water. there are 454gm in a pound so find the weight of compost in a cubic foot and do the math
A square yard is a measurement in 2 dimensions, length and width. Since there is no depth measurement in a square yard, therefore, a square yard of water has no weight. However, "...a cubic yard is 27 cubic feet, and a cubic foot of water weighs about 62.4 pounds, so 62.4 x 27 gives you...about 1685 pounds." (http://saluqi.home.netcom.com/ticklinx1.htm)
One inch of rain over one square foot is 1/12 cubic foot of water. A cubic foot of water weighs about 62.4 pounds. 1/12 of that is about 5.2 pounds.
There is 1g of water for each 1cm(cubed) of water. So you can work it out from that.
