how to convert 1kg of LPG to liters

hiii all

how to convert LPG from kg to liters? pls suggest.

You need the density, which itself can vary depending on conditions.

Some examples; butane is approximately 0.505 kg/L and propane is about 0.575 kg/L.


I could be completely off, though.

additionally, LGP is comprised of a varying ratio of butane to propane (and sometimes, minute amounts of other fuels [~1%]) LPG, generally, is seasonal, with a higher percentage of butane in the fuel during the summer months, and a higher percentage of propane in the fuel during the winter months

Varieties of LPG bought and sold include mixes that are primarily propane, mixes that are primarily butane, and the more common, mixes including both propane (60%) and butane (40%), depending on the season—in winter more propane, in summer more butane. Propylene and butylenes are usually also present in small concentration.

I found a page here that lists the density.
http://www.aegpl.com/htgb/0007.htm

Liquid density at 15º C is 500 to 510 kg/m³, that would be about 0.505 kg/L

kilograms of LPG / 0.505 kg/L = liters of LPG

How to convert 1kg of LPG to liters?

I could be right this is what I think

LPG is a mixture of Propane and butane Gas the mixture varies.

But this is how I worked it out Propane = 1.95 litres per Kilogram Butane 1.74 Litres per Kilogram.

1.95 + 1.74 = 3.69 / 2 = 1.85

6 kilo bottle of propane from calor gas costs £15.49

6 Kilos x 1.85 litres = 11.1 litres x 40.9 LPG price at filling station = 453.99

453.99 / 100 = £4.54

£15.49 - £4.54 = Ripped off by £10.95

Solution buy a refillable bottle problem very expensive do not try to fill calor gas bottles the bottle needs special pressure and blow off valves which standard bottle don't have.

A standard bottle is filled by weight and The ones that you can refill yourself is filled by pressure and thats my answer.

is useful in suggesting 1 litre of LPG accounts for 1.8 kilo's of CO2-e and 1 Kilo of LPG accounts for 3.3 kg's of CO2-e - so, approx 1.82 litres of LPG to a kilo

In trying to tie up solar water collector calculations I have this problem as well - so now the question is are you guys talking about about LPG in the gaseous or the liquid form when you mention litres?

I have it from Calor Gas
calor.co.uk/faq/general.htm
that their LPG is equivalent to
13.62 kwh/kg propane or
13.83 kwh/kg butane.

From elsewhere: it may be that
1 kg of liquid = 95L of gas or
1L liquid = 250 L of gas
and
95 kj/L
or
24,700kj/L but is this liquid or gas litres?

It is confusing.

I know Calor charge me per liquid litre - and charge too much, but that's a different story.

I am trying to use heat captured by solar collector to give kwh heat equivalent (got that OK) and litres LPG saved from burning hence cost saved (still working on that).

I ckecked the site. Your figures per kg are reversed, butance has the lower energy content per kg. Since commercial gas is not 100% pure, an analysis from your source is probably the best number. For comparison with other figures note that 1 kWh = 3600 kJ = 3.6 MJ

The kilogram of gas will supply the same energy as a liquid or a gas; you just have to know how big it is in those states if you wish to work by volume.

Liquid propane is about. 0.507 kg/L, and liquid butane -.585 kg/L. Thus, 7.01 kWh/L for liquid propane, 7.97 kWh/L for liquid butane.

As a gas, propane has a molecular weight of 44 g/mol, and ideal gas has a molar volume of 22.414 L at 0 degrees C, 1 atm (the conditions for Nm^3). Thus gas density is about 1.963 kg/nm^3. 1 kg should occupy 509 L as a gas. Note that is at 0 C and varies with absolute temperature.

These figures appear reversed, compared to other sources. Butane is heavier.
