How many litres are there in a 47kG cyclinder?

I reckon it is 24150 l, so 0.11p/l for 47kg at 26.50. How does that
compare with bulk LPG?

I read that the propane density is 500kg per m^3, lpg is a mixture but
principally propane, that gives me 94 litres to the 47kg cylinder and
at GBP26.5 for 47kg about 27.5p/ltre, 4.3p/kWhr.

That's far more like it. Bulk was 23p/litre when we had it and when it when
up for the fourth time in a year I told them to come collect their tank and
put in oil.

Of course oil prices then went into overdrive as well but that's another
story :-)
