Convert kilograms of LPG to liters of liquid gas. Set the propane/butane mix and temperature to match your cylinder.
How KG to Liters LPG Works?
KG to Liters LPG works by dividing the mass of liquefied petroleum gas (LPG) in kilograms (kg) by the density of liquefied petroleum gas (LPG) in kilograms per liter (kg/L). LPG (Propane/Butane) has a density of 0.550 kg/L at 15 °C (59 °F). The volume updates in real time as the weight changes.

14.2 kg of LPG (Propane/Butane) ÷ 0.550 kg/L = 25.82 L (6.82 US gallons, 5.68 UK gallons).
4 steps to convert liquefied petroleum gas (LPG) from kg to liters
Choose the direction: "kg → Liters" for mass to volume or "Liters → kg" for volume to mass.
Enter the weight in 1 of 7 mass units: kilograms (kg), grams (g), pounds (lb), ounces (oz), stone (st), tonnes (t) or milligrams (mg).
Set the liquid temperature: the converter applies the density of liquid LPG (Propane/Butane) at that temperature.
Read the volume in 1 of 13 volume units, including liters (L), milliliters (mL), US gallons (gal), UK gallons, US cups, cubic meters (m³) and oil barrels (bbl).
The converter changes the input to kilograms, divides the kilograms by the density and changes the liters to the selected output unit. The live container fills to the result, and the container row counts 14.2 kg domestic cylinders, 19 kg commercial cylinders and 47.5 kg cylinders.
KG to Liters LPG Formula
The KG to Liters LPG formula is liters = kilograms ÷ 0.550, written as V = m ÷ ρ with ρ = 0.550 kg/L for LPG (Propane/Butane). The formula has 3 variables:
V (volume) is the result in liters (L).
m (mass) is the weight of liquefied petroleum gas (LPG) in kilograms (kg).
ρ (rho, density) is the mass of liquefied petroleum gas (LPG) per unit volume in kilograms per liter (kg/L).
VolumeV = m ÷ 0.550
Massm = V × 0.550
Densityρ = m ÷ V

3 worked examples of the KG to Liters LPG formula
1 kg ÷ 0.550 kg/L = 1.818 L (0.48 US gal).
14.2 kg ÷ 0.550 kg/L = 25.818 L (6.82 US gal).
100 kg ÷ 0.550 kg/L = 181.818 L (48.03 US gal).
The reverse formula is kilograms = liters × 0.550: 1 L of LPG (Propane/Butane) weighs 0.550 kg (550 g, 1.21 lb), and 1 US gallon weighs 2.08 kg (4.59 lb).

Liters in 1 kg of 6 substances. Bars longer than water mark substances lighter than water.
1 liter equals 1,000 milliliters (mL), 0.264 US gallons, 0.220 UK gallons and 33.8 US fluid ounces (fl oz), so each value in the table converts to these units by multiplication.
What Is KG to Liters LPG?
KG to Liters LPG is a mass-to-volume conversion that turns the mass of liquefied petroleum gas (LPG) in kilograms (kg) into the volume in liters (L), using the density of liquefied petroleum gas (LPG) as the conversion factor.
Liquefied petroleum gas (LPG) is a mix of propane and butane stored as a liquid under pressure. LPG weighs 0.51–0.58 kg/L as a liquid at 15 °C (59 °F), with a typical value of 0.550 kg/L.
1 kg of LPG (Propane/Butane) fills 1.818 L (1,818 mL, 61.5 US fl oz).
1 L of LPG (Propane/Butane) weighs 0.550 kg (550 g, 1.21 lb).
LPG (Propane/Butane) is 45% lighter than water, so 1 kg of LPG (Propane/Butane) fills 0.818 L more than 1 kg of water.

1 kg of 4 substances fills 4 different volumes.
The International Bureau of Weights and Measures (BIPM) defines the kilogram (kg) as the SI base unit of mass, and the liter (L) equals 1 cubic decimeter (dm³), a unit accepted for use with the International System of Units (SI).

Burner run time: A burner using 0.5 kg/h of LPG burns 0.91 L of liquid per hour.
KG to Liters LPG returns estimates from typical density values. Weigh 1 L of the product or read the product data sheet, if the job needs an exact figure.
Frequently Asked Questions
How many liters is 1 kg of lpg?
About 1.818 L, using a typical density of 0.550 kg/L for lpg (propane/butane).
How much does 1 liter of lpg weigh?
About 0.550 kg (550 g).

About 25.82 L of liquid LPG for a typical 40/60 propane/butane mix at 15 °C.
How many liters is 1 kg of LPG?
About 1.8–2.0 L of liquid, depending on the propane/butane mix and temperature.
Is this the volume of gas or liquid?
Liquid. LPG is stored as a liquid under pressure. For gas volume at atmospheric pressure, use the gas calculator.
Is lpg lighter than water?
Yes. At 0.550 kg/L it is 45% lighter than water, so 1 kg takes up more than 1 liter and it floats.
