A tank volume calculator, also known as a tank size calculator, is a quick and easy way to convert the height, width and length of your tank into a volume format. Just make sure you are using the proper dimensions/dimension and appropriate sizes/size. Once you have these calculations, you can create a handy chart for later.

EXAMPLE 1: The rectangular tank

A classic problem faced by anyone who owns a home aquarium is how to calculate the volume of your fish tank so that you know the proper amount of food to add to the tank, as well as the appropriate fish stocking level.

If you have a regular fish tank you’re in luck, since the mathematical formula is relatively straightforward. The volume of your tank is simply calculated as: V(tank) = lwh. Here, l = length, w = width and h = height.

EXAMPLE 2: The cylindrical tank

There are two types of cylindrical tanks: one type that lies on its side, and another type that’s meant to stand upright. Classic uses for these two types of cylindrical tanks include using them to store fuel, oxygen or oil. Let’s look at how to calculate the volume of both of these tanks using tank capacity calculators or a cylindrical tank calculator.

In the case of the horizontal cylindrical tank, you need to calculate the area of a cross-section of the tank and then multiply this figure by the total length of the tank. The area of a cylindrical object is calculated as πr2, where r is the radius. Then, multiply that area by the length (l) of the tank, as in: V(tank) = πr2l

In the case of the vertical cylindrical tank, you need to perform the same type of measurement. However, since the tank is standing upright rather than lying on its side, you would replace the total length of the tank by the total height of the tank. Thus, the final calculation becomes the following: V(tank) = πr2h

EXAMPLE 3: The capsule tank

The final example is a capsule tank, which is a type of tank with curvatures on both ends. This type resembles a pill that you might ingest. A classic example of a capsule tank is an expansion tank, which is a small tank used to protect closed heating systems and domestic hot water systems from excessive pressure.

For measurement purposes on your tank chart calculator or expansion tank calculator, consider the capsule as a sphere of diameter d split in half and separated by a cylinder of diameter d and height h, where r = d/2.

V(sphere) = (4/3)πr3, and
V(cylinder) = πr2h, therefore
V(capsule) = πr2((4/3)r + a)

**

Just remember to convert your final measurement into the proper unit of volume for your tank mix calculator (e.g. gallons/gallon). The U.S. gallon is used in the United States and is equal to exactly 231 cubic inches or 3.785411784 litres . This can help you to calculate the weight with the tank calculator/calculators.
