To cover an area of 1 square foot with 1/2 inch of water, you would need 0.623 gallons of water.
The volume of water in 1 square inch depends on the depth of the water. For example, if you have 1 square inch of water that is 1 inch deep, it would contain approximately 1 cubic inch of water, which is about 0.0164 liters or 0.0043 gallons. Without a specified depth, it's impossible to determine the exact amount of water.

An area of 1 square inch!
Taking 1 inch to be about 2.5cm, an inch of rain on an area of 1m2 is approximatley 0.025m3, or 25000cm3. That is 25000ml or 25l of water.
If it rained 1 inch thick water over 1 square mile, the volume of that water would be approximately 2,323,200 cubic feet. That is equal to 65,785,698.28 kilograms, or 145,030,199 pounds.
One square inch is a square that is 1 inch wide and 1 inch tall.

The area of a square is calculated by multiplying the length of one side by itself. In this case, if the square has a side length of 1 inch, you would multiply 1 inch by 1 inch, which equals 1 square inch. Therefore, the area of a 1 inch square is 1 square inch.
-- 1 square inch weighs nothing, since its volume is zero. -- If the square inch is one end of a vertical column of water, then the column weighs about [ 5pounds 31/3ounces ] for each 12-ft of its height.

One square foot of water that is 1 inch deep weighs approximately 0.578 pounds. This is calculated based on the fact that 1 cubic foot of water weighs about 62.4 pounds, and since there are 12 inches in a foot, 1 inch of water in a square foot amounts to 1/12 of a cubic foot. Thus, the weight is 62.4 pounds divided by 12, which equals around 5.2 pounds per inch, and for 1 square foot, it totals to approximately 0.578 pounds.
