Calculate the volume and capacity of a flat horizontal oval tank or container. The oval tank used here has a rectangular shape with two semi-sphere ends. This calculator uses centimetres for measurements.

Approximate weight of Fuel or Water

one litre of water = 1 kilogram
one litre of diesel fuel = 0.832 kilogram
one litre of gas = 0.75 kilogram 

Calculator

1. enter the height of the tank in centimetres
2. the width of the tank in centimetres
3. the length of the tank in centimetres
4. the weight of the liquid in kilograms per litre

Results

1. the volume of the tank in cubic centimetres
2. the volume in cubic metres
3. the volume in cubic inches
4. the volume in cubic feet
5. the capacity of the tank in centilitres
6. the capacity in litres
7. the capacity in US gallons
8. the capacity in Imperial gallons
9. full tank liquid weight based on kilograms/L
10. the surface area of the tank in square centimetres
11. the surface area in square metres
12. the surface area in square inches
13. the surface area in square feet

Formula

V  = (𝝅 R² + 2RS)L
where V is the volume
𝝅 = 3.14159265
R half the height of the tank
S  the width minus height
L the length
