How many Kilograms are in 4000 liters?

Answer 1

This question cannot be answered sensibly. A litre is a measure of volume, with dimensions [L3]. A kilogram is a measure of mass, with dimensions [M]. Basic dimensional analysis teaches that in most cases you cannot convert between measures with different dimensions without additional information. It requires only a little imagination to compare a litre of air and a litre of water and conclude that the first will have a much smaller mass than the second. There is no direct relationship between volume and mass.

Answer 2

The number of kilograms in 4000 liters depends on the substance being measured. To convert liters to kilograms, you need to know the density of the substance. The formula to convert liters to kilograms is: mass = volume (liters) x density (kg/L).
