# Horizontal Oval Flat Tank Volume and Surface Area - Metres

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

Note: The width measurement has to be larger than the height measurement!

### Horizontal Oval Tank - Metres

#### Calculator

- enter the height of the flat horizontal oval tank in metres
- the width of the tank in metres
- the length of the tank in metres
- the weight of the liquid in kilograms per litre

#### Results

- the volume of the tank in cubic metres
- the volume in cubic centimetres
- the volume in cubic inches
- the volume in cubic feet
- the capacity of the tank in litres
- the capacity in hectolitres
- the capacity in US gallons
- the capacity in Imperial gallons
- full tank liquid weight based on kilograms/L
- the surface area of the tank in square metres
- the surface area in square centimetres
- the surface area in square inches
- 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
