One kiloliter is equal to 1,000 liters, so to convert kiloliters to liters, simply multiply the number of kiloliters by 1,000. If, for example, there are 5 kiloliters of water in a tank, the tank contains an equivalent of 5,000 liters of water. A liter is slightly more than a quart, with the exact equivalent being 1.1365225.
A liter is a measure of volume currently defined as being equal to that of a cube with sides all measuring 10 centimeters. A cubic foot would contain 27 such cubes, which makes a cubic foot equal to about 27 liters. Between 1901 and 1964, a liter was defined as being equal to 1 kilogram of pure water at standard pressure and maximum density. The definition has since been replaced by the current definition because of the mass-volume ratio of water being dependent on additional factors such as isotopic uniformity and temperature.
Fluids and solids that can be poured are usually measured in liters and are based on the volume capacities of their containers. Cubic meters are commonly used for items measured by their displacements or dimensions. The liter is accepted for use with the International System of Units, or SI, but not as an official unit. The cubic meter is the SI unit of volume.
