"If your measure is in cubic feet, multiply by 2.83 to convert to meters."
Which is *completely* non-intuitive, as there are approximately 36 cubic feet in a cubic meter. But it seems to be just the way the meters are set up. But it's utterly baffling for someone who has been keeping a record of their gas usage!
So if anyone is worried why their new smart gas meter is suddenly logging 3 times the usage of their old meter. Don't worry!
