How many kilograms are in 6 liters of water?
How many kilograms are in 6 liters of water?
Answer
The density of water is 0.998 kg/L (liquid water at 20 °C; rounding to 1.00 kg/L is fine for everyday use).
How the mass of 6 liters of water was worked out
0.998 kg/L × 6 L
≈5.99 kg
The density comes from FAO/INFOODS Density Database v2.0. Liquid water at 20 °C; rounding to 1.00 kg/L is fine for everyday use.
Why a liter and a kilogram are not the same thing
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.
If the substance is not known in advance, start from how many kilograms are in 6 liters — the same volume across every substance at once.
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.
For water that means 6 liters weighs 5.99 kg here, and one kilogram of it takes 1 liter there.
