For example, for a cone bottom tank, if the level is below the cone edge one doesn't need to consider the cylinder part of the tank at all. The filled volume calculation itself usually consists of adding up parts of the tank volume depending on how high the liquid level is. Note that this is easier to do with oils compared to water. If the tank has no visible level meter or gauge and it is safe to open it, its level could be measured by descending a clean and dry rod to the bottom of the tank, then retracting it and measuring the level the liquid reached. The volume (in m 3 or ft 3) and liquid volume (in gallons or litres) of a liquid poured in a tank can be calculated easily assuming the tank is sitting with its bottom perpendicular to the ground surface (it is not tilting) and there is a way to measure the liquid level. Calculating the volume of a liquid in a tank Obviously, if using our tank capacity calculator all this work is performed automatically for you. The usual volume formulas for these figures are used. Similarly, a dome top tank's volume is calculated as the sum as the volume of a half-sphere and a cylinder. For complex shapes such as dome tops, cone tops or bottoms, oblique cone bottom, ovals, and capsules, the tank volume is calculated as a sum of the component simpler shapes.įor example, the volume of a capsule tank is calculated as the sum of a sphere and a cylinder, whereas a cone bottom tank's capacity is estimated by summing the volume of the cone and the volume of the cylinder. It can be used as a water tank calculator, oil tank calculator, fuel tank calculator, and so on.įor simple tanks such as rectangular prisms or cylinders the calculation is straightforward and exactly the same as the ones used in our cylinder volume and box volume calculators. Note that the tool does not differentiate tanks based on their purpose or the liquid they contain. (note: calculation presumes the dome is half a sphere) (note: calculation presumes each end is half a cylinder) (note: calculation presumes each end is half a sphere) It contains notes regarding important assumptions and illustrations of the necessary dimensions for volume calculations for each shape: Tank shapes supported in the calculator Tank shape Supported tank shapesīelow is a list of tank shapes supported by the calculator.

It will also output the percentage of the tank capacity in use based on the liquid level (liquid height) entered. It will also output liquid maximum volume in litres (liters), US gallons, UK gallons, and BBL (US Oil barrels) and similarly for the liquid volume of the liquid in the tank. The tank volume calculator will output the volume in cubic meters and cubic feet and used capacity in the same metrics. Supported tank measurements are in mm, cm, dm, meters, inches, feet, and yards. Also, real tanks might have tubing or detectors on the inside which might take space not accounted for in the output of this tool. a perfect half-sphere for domes and perfect half-cylinders for ovals. It should be noted that all calculations should be treated as estimates for real-life purposes since they assume certain perfection in the shape of the tank - e.g.

If these are not available, you should make sure to account for the thickness of the tank walls in your volume calculations. When filling the dimensions, make sure to use the inner dimensions of the tank. You can also enter the height of the liquid currently present in the tank to get an estimate of its volume, liquid volume, and the percentage of the tank capacity currently in use.

To use the calculator, simply select the shape of the tank, then fill in the respective dimensions, then click calculate to see the results. The calculator is useful in planning tank capacity in construction projects, water purifier plants, oil storage systems, and others. tank capacity), liquid volume, and the volume of the liquid currently in the tank. This tank calculator is a versatile tool allowing to calculate tank volume (a.k.a.
