Gas

[le canichot depang]

Can one of our wise men on the forum tell me how you measure gas, we have just put 25litres into our gasflow bottles at the pumps, but wonder how it compares in weight to the old 7Kg bottles we had, there is probably a mathematical equation for this but I have no idea, any help appreciated - thank you

1 kilo equals 2 lt of gas. 25 lt therefore equals 12 1/2 kilos.

if you want to split hairs 0.55 litres =1 kilo but remember the tank will only fill to 80% of its capacity toprevent any chance of liquid gas entering the system.

Also worth noting that LPG works out at around 45p a Litre so with my 2 x 11Kg bottles (44 Lts) that is equivalent to £19.80 which i think is somewhere around what it costs for a 6Kg Calor Gas refill (Although in practice I would only fill to 80%).

Thank you all for your replies, I can now understand it all - much cheaper :-D

You have your thoughts reversed - easy done!

 

To be specific (no pun intended ..specific gravity??!!) the data is as follows.

 

At 15 degrees Centigrade

liquid Butane 1 litre = 0.576 Kg. ( 1.736 litre = 1 Kg)

liquid Propane 1 litre = 0.508 Kg ( 1.967 litre = 1 Kg)

 

Lpg often is a mixture of the two so 0.55Kg /Litre is a generally a figure close enough and easy to remember.
