# Oval Tank Horizontal - Millimetres Calculate the volume and capacity of a horizontal oval tank. The oval tank used here has a rectangle shape with two semi-circular ends. This calculator uses millimetres 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 - Millimetres

In Cubic Metres
In Cubic Feet ft³
###### Tank Capacity
In Litres L
In US Gallons gal US
In Imperial Gallons gal Imperial
Weight of Liquid kg

#### Calculator

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

#### Results

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

##### 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 millimetre (mm³) = 0.000000001 cubic metres (m³)
one cubic millimetre (mm³) = 0.0000000353146667214886 cubic feet (ft³)
one cubic millimetre (mm³) =  0.000001 litres (L)
one cubic millimetre (mm³) = 0.000000264172052358148 gallons (gal) US
one cubic millimetre (mm³) = 0.000000219969248299088 gallons (gal) Imperial
