Elliptical Cylinder Tank - Metres

Elliptical Cylinder Tank

Calculate the volume and capacity of a elliptical cylinder tank.
The elliptical tank here looks like a squashed circle, and in a vertical ellipse shape, the width has to be smaller than the height of the tank. 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

Note: measurements used in the calculation are diameter lengths, not radius lengths!

  1. enter diameter A of the tank in metres
  2. diameter B of the tank in metres
  3. the height of the tank in metres
  4. the weight of the liquid in kilograms per litre


  1. the volume of the elliptical cylinder tank in cubic metres
  2. the volume in cubic feet
  3. the capacity in litres
  4. the capacity in US gallons
  5. the capacity in Imperial gallons
  6. full tank liquid weight based on kilograms/litre

V= 𝝅HWL/4
where V is the volume
𝝅 = 3.14159265
H is the height of the tank
W half of diameter B
L half of diameter A
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
