To convert liters of gas per cubic meter, divide the number of liters per 1000.

To convert cubic meters of gas per liter use the inverse rule:Multiply the number of cubic meters of gas in 1000.
form of formulas, these simple rules can be written as follows:
km³ = C / 1000,
km³ = Cl * 1000,
where:
cubic kilometers - the number of cubic meters, and Cl - number of liters.

As a rule, the volume is measured in liters of liquid (which is under high pressure or at low temperature) gas contained in the various containers (cylinders).In cubic meters generally measure the volume of gas at atmospheric (or s
mall) pressure.To convert liters of liquefied gas in cubic meters of conventional gas is necessary in addition to the number of liters to know its chemical composition, pressure, temperature or density and mass.However, note that the cylinders are usually filled with liquefied gas by not more than 80%.
estimates the possible adoption of the following fact: the evaporation of one liter of liquefied gas (propane) produced 200 liters of gas.Ieto transfer the amount of liquefied gas in liters per cubic meter, use the following formula:
km³ = C / 5
where Cl - number of liters of liquefied gas.

example.

What gas flow rate will household gas meter, if the skip through standard household gas cylinder?
decision.
Standard "propane" gas tank has a volume of 50 liters.Household (cooking) gas is a mixture of propane and butane.Standard filling contains 21 kg of a gas mixture.Since the molar mass of propane and butane - are different, and the ratio of gases is usually unknown, using the above formula, we get:
km³ = 50/5 = 10 cubic meters.

for compressed gases (not to be confused with liquefied), use the following approximate formula:
km³ = Cl * D / 1000,
where D - the gas pressure in the atmosphere.

example.

What amount of oxygen contained in the standard tank at a pressure of 250 atmospheres?
decision.

for storage of gases such as nitrogen, argon, oxygen, apply 40-liter cans.Therefore, the amount of oxygen at normal (atmospheric) pressure will be:
km³ = 40 * 250/1000 = 10 cubic meters.
