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

Calculator

1. enter the height of the tank in feet
2. the width of the tank in feet
3. the weight of the liquid in pounds per US gallon

Results

1. the volume of the ellipse tank in cubic feet
2. the volume in cubic inches
3. the volume in cubic metres
4. the tank capacity in US gallons
5. the capacity in Imperial gallons
6. the capacity in litres
7. full tank liquid weight
8. the surface area of the tank in square feet
9. the surface area in square inches
10. the surface area in square millimetres
11. 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
