Calculate the volume and capacity of a truncated cone tank. A truncated cone tank is a cone where the top part is cut off parallel to its base. 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

Calculator

1. truncated cones' height in millimetres
2. the top diameter in millimetres
3. base diameter in millimetres
4. the weight of the liquid in kilograms per litre

Results

1. the volume of the truncated cone tank in cubic millimetres
2. the tank volume in cubic metres
3. the volume in cubic feet
4. the tanks' 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 = 1/3𝝅((T/2)²+(T/2)(B/2)+(B/2)²);H
where V is the volume of the truncated cone
𝝅 = 3.14159265
T the upper diameter
B the lower diameter
H the height of the truncated cone
