How much does 1 liter of propane weigh?
Answer
The density of propane is 0.5076 kg/L (liquid propane at 15 °C, or 59 °F; it gets lighter as it warms), so one liter of it weighs 1.12 lbs.
In kilograms, 1 liter of propane is 0.51 kg — the same density, answered by the liters to kilograms page.
How the weight of 1 liter of propane was worked out
A pound is exactly 0.45359237 kilograms, so the density in kilograms per liter turns into pounds per liter by dividing by the pound.
1 L × 0.5076 kg/L ÷ 0.45359237
≈1.12 lbs
(one point one two lbs)
The density comes from ISO 3993:1984: liquid propane at 15 °C, or 59 °F; it gets lighter as it warms.
Why the same liter weighs differently
A liter measures volume, a pound measures weight, and density is what ties them together: how many pounds one liter of this particular substance comes to. Water is the everyday reference at 2.2 lbs per liter, and everything else sits above or below it.
Across this page the spread is wide: one liter of propane weighs 1.12 lbs, one liter of water 2.2 lbs — at the very same volume.
If the substance is not known in advance, start from how many pounds 1 liter is — the same volume across every substance at once.
The other way round: how many liters a weight fills
This page starts from a volume and answers in pounds. The opposite question — how many liters a given weight comes to — is what the pounds to liters calculator is for, and in metric units the same question is kilograms to liters. All of them read one density table, so their numbers agree.
For propane that means 1 liter weighs 1.12 lbs here, and one pound of it fills 0.89 liters there.
