How many kilograms are in 4,500 liters?
How many kilograms are in 4,500 liters?
Answer
The question does not name a substance, and there is no single number for it: a liter fixes the volume, the weight comes from the density. For instance, 4,500 liters of water is 4,491 kg, while 4,500 liters of gasoline is 3,330 kg. The table below covers every substance.
Why a liter has no single weight
A liter measures volume, a kilogram measures mass, and density is what ties them together: how many kilograms one liter of this particular substance comes to. The coincidence that makes people treat them as one thing is historical — in 1795 the gram was defined as the mass of one cubic centimeter of water, so a liter of water weighed a kilogram by construction. For anything else the equality breaks.
The extremes of this page make it obvious: one liter of LPG weighs 0.51 kg, while one liter of densely packed sand weighs 2 kg — four times more at the very same volume.
The other way round: how much room a kilogram takes
This page starts from a volume and answers in kilograms. The opposite question — how many liters a given mass comes to — is what the kilograms to liters calculator is for. Both read the same density table, so the two pages agree wherever the answer is volume times density.
