How many liters are in 50 kilograms of LPG?

Answer

50 kilograms of LPG takes
98 L

The density of LPG is 0.51 kg/L (liquid phase at 15 °C: propane 0.5076, n-butane 0.5845. A propane–butane mix has no single density — it depends on the blend).

How the volume of 50 kilograms of LPG was worked out

volume = mass ÷ density

50 kg ÷ 0.51 kg/L

98 L

The density comes from ISO 3993:1984. Liquid phase at 15 °C: propane 0.5076, n-butane 0.5845. A propane–butane mix has no single density — it depends on the blend.

The other way round: what a liter of this weighs

This page starts from a mass and answers in liters. The opposite question — how much a given volume weighs — is what the liters to kilograms calculator is for. Both read the same density table, so the two pages agree wherever the answer is volume times density.

For LPG the density is 0.51 kg/L, so 50 kilograms takes 98 liters — and one liter of it weighs 0.51 kg.

Volume of the liquid, not the size of the cylinder

The number above is how much room the liquid phase occupies. A cylinder holding this much gas has to be larger: it is never filled to the brim, because expanding vapour needs room above the liquid. That is why filling limits are set in mass rather than as a share of the volume.

About "Kilograms to Liters" Calculator

This calculator converts kilograms to liters through the density of the substance: volume equals mass divided by density. The heavier the substance, the less room the same kilogram takes — one kilogram of honey is 0.7 liters, while one kilogram of liquefied gas is almost two. For example, it can help you find out how many liters are in 50 kilograms of LPG? (The answer is: 98). For bulk materials the answer is a range, and it is inverted against the weight page: the denser the packing, the smaller the volume of the same mass.

FAQ

How many liters are in 50 kilograms of LPG?

50 kilograms of LPG takes 98 L

How do you work out the volume of 50 kilograms of LPG?

Volume equals mass divided by density. The density of LPG is 0.51 kg/L and the mass is 50 kilograms, which gives 98 liters — the figure on this page is rounded, so dividing the two printed numbers can differ in the last digit.

How accurate is the density of LPG?

The figure comes from ISO 3993:1984. Liquid phase at 15 °C: propane 0.5076, n-butane 0.5845. A propane–butane mix has no single density — it depends on the blend.

And how much does 50 kilograms of LPG weigh per liter?

That is the opposite question, and it has its own page: one liter of LPG weighs 0.51 kg. This page starts from the mass and answers in liters; that one starts from the volume and answers in kilograms.
