Concrete Floor Calculator

This one is aimed at an interior floor rather than a single rectangle of concrete: give it the total square footage, or the length and width of up to three rooms, plus the slab thickness. It returns the volume in cubic yards, cubic feet and cubic metres, how many ready-mix loads that is at your truck capacity, what the concrete costs at your price per yard, and the bag count for a 40, 60 or 80 pound mix. A waste allowance is added on top because a screeded floor never comes out at the theoretical volume. Vapour barrier, base gravel, mesh and rebar are not counted, and a short-load fee from the plant is not either.
