Question: how many litres of water make 1 unit?
Answer: There are 10 deciliters = 1,000 milliliters = 1,000 cubic centimeters = 1.057 quarts = 33.814 ounces in a liter. Because water has a density of 1.0, one liter of water weighs 1,000 grams = 1 kilogram. This is the volume of a cube 1 meter (see distance units) on each side. One cubic meter = 1000 liters.
