KG To Liters

KG to Liter Propane

Convert kilograms (or pounds) of propane to liters of liquid. Propane expands strongly with temperature, so set the tank temperature.

How KG to Liter Propane Works?

KG to Liter Propane works by dividing the mass of propane in kilograms (kg) by the density of propane in kilograms per liter (kg/L). The converter holds 2 gases from 0.507 kg/L (liquid propane) to 0.584 kg/L (liquid butane), and the default is liquid propane at 0.507 kg/L. The volume updates in real time as the weight changes.

Mass9.07 kg
÷ Density0.507 kg/L
Volume17.89 L
9.07 kg of liquid propane ÷ 0.507 kg/L = 17.89 L (4.73 US gallons, 3.94 UK gallons).

5 steps to convert propane from kg to liters

  1. Choose the direction: "kg → Liters" for mass to volume or "Liters → kg" for volume to mass.
  2. Select 1 of 2 gases: liquid propane and liquid butane.
  3. Enter the weight in 1 of 7 mass units: kilograms (kg), grams (g), pounds (lb), ounces (oz), stone (st), tonnes (t) or milligrams (mg).
  4. Set the liquid temperature: the converter corrects the density of liquid propane by 0.28% per °C (0.156% per °F) from 15 °C.
  5. 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 20 lb BBQ tanks, 100 lb cylinders and 500 gal tanks at 80% (1,514 L).

KG to Liter Propane Formula

The KG to Liter Propane formula is liters = kilograms ÷ 0.507, written as V = m ÷ ρ with ρ = 0.507 kg/L for liquid propane. The formula has 3 variables:

  • V (volume) is the result in liters (L).
  • m (mass) is the weight of propane in kilograms (kg).
  • ρ (rho, density) is the mass of propane per unit volume in kilograms per liter (kg/L).
m ρ V
VolumeV = m ÷ 0.507
Massm = V × 0.507
Densityρ = m ÷ V

3 worked examples of the KG to Liter Propane formula

  1. 1 kg ÷ 0.507 kg/L = 1.972 L (0.52 US gal).
  2. 9.07 kg ÷ 0.507 kg/L = 17.89 L (4.73 US gal).
  3. 100 kg ÷ 0.507 kg/L = 197.239 L (52.1 US gal).

The reverse formula is kilograms = liters × 0.507: 1 L of liquid propane weighs 0.507 kg (507 g, 1.12 lb), and 1 US gallon weighs 1.92 kg (4.23 lb).

Temperature correction formula for liquid propane

The corrected density is ρ(T) = ρ15 ÷ (1 + β × (T − 15)), with β = 0.0028 per °C for liquid propane. Liquid propane at 35 °C (95 °F) weighs 0.480 kg/L, so 1,000 kg fills 2,082.84 L instead of 1,972.39 L at 15 °C.

KG to Liter Propane Conversion Table

The KG to Liter Propane conversion table lists the volume of liquid propane in liters (L), US gallons and UK gallons for 12 masses from 0.5 kg to 1,000 kg at 0.507 kg/L. A second table lists 1, 5, 10, 25 and 50 kg for all 2 gases.

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 Liter Propane?

KG to Liter Propane is a mass-to-volume conversion that turns the mass of propane in kilograms (kg) into the volume in liters (L), using the density of propane as the conversion factor.

Propane (C₃H₈) is a hydrocarbon gas stored as a liquid under pressure in cylinders and tanks. Liquid propane weighs 0.507 kg/L at 15 °C (59 °F), and butane (C₄H₁₀) weighs 0.584 kg/L.

  • 1 kg of liquid propane fills 1.972 L (1,972 mL, 66.7 US fl oz).
  • 1 L of liquid propane weighs 0.507 kg (507 g, 1.12 lb).
  • Liquid propane is 49.3% lighter than water, so 1 kg of liquid propane fills 0.972 L more than 1 kg of water.
Liquid Propane1.97 L
Water1.00 L
LPG (Propane/Butane)1.82 L
LNG2.22 L
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).
