### History of Liter

There was an issue from 1901 to 1964 when atmospheric pressure was defined as the amount of one kilogram of pure water per liter in terms of maximum density. However due to the mass-volume relationship of water many factors can be found to control. And the definition of the liter was changed to its previous and current definition due to the discovery that the prototype of the kilogram was slightly larger.
