Xeolyte, 1 liter (litre if you will--I'm American, so I will spell it the American way) is defined to be 1000 milliliters. 1 milliliter is in turn defined to be 1 cubic centimeter. 1 centimeter is defined as 0.01 meters. 1 meter is defined as the distance traveled by a wave of light in a vacuum in 1/299792458th of a second. 1 second is defined by the rate of radioactive decay of a certain isotope of Cesium.
I have just given you a very precise (though very impractical) way of determining the physical value of one liter. Oh, whoops--you meant another kind of value :P Well, yes, it is meaningless to give value to a liter--you need a liter of something (even if that something is nothing) before it becomes meaningful to say it has value.
