As defined by the SI units, water weighs almost exactly 1 kilogram per liter (at 4 °C, slightly less at higher temperatures).
So 4 kilograms of water would be about 4 liters of water.
This depends one what is being measured. A kilogramme is a measure of weight. A gallon is a measure of volume A gallon of water would weigh more than a gallon of oil.
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.
7,500 grams would equal to 7.5 kilograms. This is because ratio of grams to kilograms is 0.001. So, 7500 grams multiply by 0.001 would equal to 7.5 kilograms.
Kilograms are a measure of mass, not volume. The volume of a given mass would depend upon the density of the substance.
0.03 kilograms would equal to 30 grams. This is because the ratio of grams to kilograms is 1:1000. So 0.03 kilograms would equal to 30 grams.
1000kg, which is the same as 1 ton
9,855 grams would equal to 9.855 kilograms. This is because ratio of grams to kilograms is 0.001. So, 9855 grams multiply by 0.001 would equal to 9.855 kilograms.
907 grams would equal to 0.907 kilograms. This is because ratio of grams to kilograms is 0.001. So, 907 grams multiply by 0.001 would equal to 0.907 kilograms.
500,000.
You could weigh it. You can also determine its density by comparing it to an equal volume of water, but first you would have to determine how much water it displaces to determine its volume.
Liters are a measure of volume. Kilograms are how you measure weight. You cannot express weight in liters unless you already know the weight of a liter of whatever it is. If you meant kilograms, the answer would be 8.8 pounds.
0.9 kilograms would equal 900 grams, so that would be larger.
