Hello, we have before to drive in winter holidays, now should be clarified in advance of the fuel for the heating. And for me not mathematicians insurmountable questions open. I buy/change my gas bottle with 11 kg gas content for approx. 16,49.- Euro. Now some campsites also offer a gas supply directly at the pitch. Here is the offer at 8,50.-Euro per m3. Now I want to calculate what is cheaper and by how much? 1 KG camping gas in the bottle is how much m3, or 1 m3 parking gas is how much KG? Can you make me know? Thanks UNO
