# Flat Horizontal Elliptical Tank - Feet

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

##### Note:

The width measurement has to be larger than the height!

##### Approximate Weight of Fuel or Water

one US gallon of water = 8.34 pounds
one US gallon of diesel fuel = 7.1 pounds
one US gallon of gas = 6 pounds

### Flat Horizontal Elliptical Tank - Feet

#### Calculator

- enter the height of the tank in feet
- the width of the tank in feet
- the weight of the liquid in pounds per US gallon

#### Results

- the volume of the ellipse tank in cubic feet
- the volume in cubic inches
- the volume in cubic metres
- the tank capacity in US gallons
- the capacity in Imperial gallons
- the capacity in litres
- full tank liquid weight
- the surface area of the tank in square feet

- the surface area in square millimetres
- the surface area in square metres

##### Formula

volume= 𝝅HWL/4
where 𝝅 = 3.14159265
H is the height of the tank
W the width
L the length
