The calculation method is as follows:

Liquefied gas: about 0.560g/ml for industrial use and 0.580g/ml for civil use.

Gaseous liquefied petroleum gas is 1.2.0 times heavier than air, and the specific gravity of air is1.293g/L. 。

Because only the density changes and the weight remains the same, it can only be counted as volume.

Taking civil use as an example, the liquid state is 580g/L, so the liquid state of 1 kg is1.72L.

If the specific gravity density of air is 1.5 times, the gas density is1.94g/L.

The volume expansion multiple of liquid to gas is 580g/L÷ 1.94g/L=298.97.

Then multiply by the liquid volume1.72l298.97x1.72 = 514.23l.
