However, there are other, more serious causes of floaters, including infection, inflammation (uveitis), hemorrhaging, retinal tears, and injury to the eye. Floaters are more likely to develop as we age and are more common in people who are very nearsighted, have diabetes, or who have had a cataract operation.
Quick Answer. One cubic meter of soil weighs between 1.2 and 1.7 metric tonnes, or between 1,200 and 1,700 kilograms. These metric figures convert to between 2,645 and 3,747 pounds, or between 2.6 tons and 3.7 tons, per cubic meter. Loose topsoil is lighter, and compacted topsoil is heavier.
The unit weight calculation is: Unit Weight = Weight of Concrete Ã· Volume of Concrete. This calculation can be rearranged for volume, which is known as the yield calculation. In other words, it is the volume that a certain weight of material will yield.rom the batch ticket, we find that 5 cubic yards of concrete were batched. The total weight of cement, sand, and stone was 18,860 pounds, and 156 gallons of water were also batched. Since we know that water weighs 8.33 pounds per gallon: 156 gallons of water X 8.33 pounds per gallon = 1,300 pounds of water.
