Calculate the amount of liquid in a partially filled flat horizontal oval tank or container.
The horizontal oval tank here has a rectangle-like center with semi-circular 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 flat horizontal oval tank in inches
2. the width of the tank in inches
3. the length of the tank in inches
4. the depth of the liquid inside the tank in centimetres
5. the weight of the liquid in kilograms per litre

Results

1. the volume of the flat oval tank in cubic centimetres
2. the volume of the tank in cubic metres
3. the volume of the tank in cubic inches
4. the volume of the tank in cubic feet
5. the total amount of liquid the tank can hold in litres
6. the amount of liquid inside the tank in litres
7. the amount of liquid inside the tank in US gallons
8. the amount of liquid inside the tank in Imperial gallons
9. the amount of liquid inside the tank in cubic metres
10. the weight of the liquid inside the tank in kilograms
11. the amount of liquid it will take to top up this tank in litres

Formula

V = 0.5r²(Y-sin(Y))L+d(W-H)
where V is the volume
r half the tanks height
Y=2cos-¹(r-d)/d
d the depth of the liquid inside the tank
W the width of the tank
H the tanks height
