# Horizontal Elliptical Tank - Flat

Calculate the volume, capacity and surface area of a horizontal flat elliptical tank/container.

The elliptical tank here looks like a squashed circle, and for this type of tank/container, the height has to be smaller than the width. This calculator uses inches for measurements.

##### Note:

The width measurement has to be larger than the height!

##### Approximate Weight of Fuel or Water
