Default convert kg in lpg (liquid) to cubic meters

Hi I am from india, we have a gas bank with liquid lpg cylinders (one cylinder is 33.3 kg), a low meter (Itron make) is installed which shows the readings in cubic meter (after vapouriser), if one kg of the liquid lpg costs 60.6 (indian rupees), what is the cost of lpg per cubic meter????

If the meter is after the vaporizer, it is measuring the gas.

1 L of liquid propane is about 0.51 kg, and when vaporized, produces about 277 L, (0.277 m) of gas

1 kg produces about 0.543 m of gas, so cost is 60 rupees/0.543 m or 110.5 rupees/m

Default conversion factor in an LPG meter (m3)

Hi Sameer here,
Thank you for your valuable reply regarding the conversion of lpg from cubic meter to kg. I have a doubt again for the flow meter that is installed. The flow meter is of ITRON make, (D-76161 Karlsruhe, M-10) installed after the vapouriser showing the readings directly in cubic meter. Does it have any multiplying factor? One conversion is shown on the meter that shows - V = 0.59 dm3 (its cube, raise to 3). I am not able to understand this. Please suggest.

So what your saying is if I have a 50 kilo tank it contains 25.5 liters of gas so why is the tank so big

You have it backwards 50 kg divided by 0.51 kg/L is 98 L.

1 Litre of liquid Propane produces 0.277 m3 of vapour But at what pressure? Is it at atmospheric pressure - or - operating pressure for LPG ie, 2.75Kpa ?

At standard atmospheric pressure, 101.325 kPa.

The 2.75 kPa is a "gauge pressure" that is, above atmospheric. But your flow device is likely calibrated at operating pressure to indicate the equivalent volume at atmospheric pressure. Absolute operating pressure is only about 3.7% higher anyway.
