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 metres 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 flat horizontal oval tank in metres
2. the width of the tank in metres
3. the length of the tank in metres
4. the weight of the liquid in kilograms per litre

Results

1. the volume of the tank in cubic metres
2. the volume in cubic centimetres
3. the volume in cubic inches
4. the volume in cubic feet
5. the capacity of the tank in litres
6. the capacity in hectolitres
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 metres
11. the surface area in square centimetres
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

Conversions

one cubic metre (m³) = 35.3146667214886 cubic feet (ft³)
one cubic metre (m³) = 1000 litres (L)
one cubic metre (m³) =  264.172052358148 gallons (gal) US
one cubic metre (m³) =  219.969248299088 gallons (gal) Imperial
