I searched the internet and found some different formulas for
calculating the volume of water used by a toilet.

I took measurements of a toilet made in the 1950's and the inside
measurements of the bowl were
18 x 14 x 9 inches . The height was measured from the bottom of the
bowl to the fill line.

Does anyone know the correct formula for calculating how many gallons
that represents?

Thanks.

Who cares about measurements of tank, to figure usage turn off water,
flush toilet, fill up till full with amount known, there is your usage.
