    Btu per cu.ft. varies by region and their source of natural gas. In my area, about 1025 Btu/cu.ft.

    I know I'll probably hear about using the dreaded Rule of Thumb but 1000 btu's/cu. ft. will get you pretty close for an initial observation.
    We've been doing so much,for so long,with so little, that now we can do almost anything, with nothing at all.

    another rule of thumb is every full revolution of the 1/2 ft dial on the gas mtr is 30,000 btu's. you clock the mtr for 1 minute 4 revs=120,000 btu's

    my meter shows in cubic meters not cubic ft, on the charts i have seen the conversions are for cubic ft. this is where i'm stuck on finding the btu input.

    I have a chart for clocking metric meters and as stated earlier on a .01 m3/rev test dial @ 19 sec/per rev you are looking at approx. 67 cubic feet /hour or 67000btuh ( based on 1000btuh/cubic foot)You can use the same formula for calculating input as you would on a standard meter using 3600 divided by the time for 1 revolution of your test dial and mutiplying by either .01 or.05 which will give you M3/HR. then multipy this by 10.35kWh/m3 which will give you the input in kilo-watts. Then knowing 1kw=3412btuh you can figure out the input.HTH

    Will this help?



    1 cubic meter is ~35.3147 cubic feet.
    1 cubic foot is ~.02831685 cubic meeters.

    I don't know if that will help you or not, but I though that you mighr be able to convert you reading into cubic feet with that.
