With the help of a tank volume calculator, you can determine the overall capacity as well as the filled volume of tanks such as water tanks and oil tanks measured in gallons and litres.
Tank volume calculator: What is it?
A tank volume calculator is a straightforward tool that provides assistance in determining both the overall volume of the tank and the volume of the portion that is filled. While the tank volume calculator is important for sizing a mixer for a tank or specifying a tank for a given volume, it can also be used on the processing floor to determine how much to fill a vessel to achieve a specified volume for a specific batch or formulation.
Tank volume calculator capacity types
The volume of water contained in the tank when it is completely filled.
The total amount of water from the bottom of the tank to the top of the overflow

Actual useable capacity
The volume of water coming from above the outlet and going into the overflow.
Tank volume calculator: Tank shapes
Many tank capacity calculators provide you with the option to choose from one of 10 different tank shapes. These are:
 Vertical cylinder
 Horizontal cylinder
 Rectangular prism (box)
 Vertical capsule
 Horizontal capsule
 Vertical oval (elliptical)
 Horizontal oval (elliptical)
 Cone’s bottom
 Cone top; and
 Frustum (truncated cone, funnelshaped)
Tank volume calculator: Formula
Tank volume calculations allow you to enter the measurements of your container, either in metric units (centimetres or metres) or imperial units (yards, feet or inches).
The volume of the rectangular tank can be calculated using the formula V = lxbxh, where
 V= volume of the rectangular tank.
 l= the length of the base
 b= width of the base
 h= height of the tank
These three dimensions have an immediate and direct bearing on the volume of the rectangular tank.

Calculating the amount of a liquid contained in a tank
The volume (in m³ or ft³) and liquid volume (in gallons or litres) of a liquid put into a tank can be readily estimated if the tank is lying with its bottom perpendicular to the surface of the ground (it is not tilting) and there is a method for measuring the liquid level. If the tank does not have a visible level metre or gauge and it is safe to open it, the level might be determined by lowering a clean, dry rod to the bottom of the tank and then measuring the liquid’s depth. This is simpler to do with oils than with water.
The fill level is used to determine how much of the tank’s capacity must be added to get the total filled volume. If the level in a conebottom tank is below the cone’s rim, for instance, the cylindrical portion of the tank is irrelevant.
To calculate the volume of a basic tank like a cylinder tank, one should just substitute the height of the tank with the height of the liquid as measured in the standard volume of a cylinder equation. Based on the calculator’s results or the tank manufacturer’s guidelines, you can quickly convert the filled volume to a percentage of the total tank capacity.

How to determine the volume of a tank?
The tank volume is found by adding the volumes of the individual forms that make up more complicated geometries, including domes, cones, oblique cones, ovals, and capsules.
The volume of a capsule tank, for instance, is determined by adding the volumes of a sphere and cylinder, whereas the capacity of a cone bottom tank is estimated by adding the volumes of a cone and cylinder. The volume of a dometopped tank is similarly determined by adding the volumes of a halfsphere and a cylinder. These numbers are calculated using standard volume calculations.
How do I calculate tank volume in litres?
You can use the conversion formula 1 litre = 1000 cm^{3}. The tank volume can be calculated in litres by diving the volume of the shape by 1,000.
What is the duration till when water is held in a tank?
This can be found out by knowing the amount of water that you have saved in the tank and the pace at which it is consumed. So, start with finding the capacity of your tank using a tank volume calculator. Then, find the amount of water stored in and what is consumed daily. Divide total quantity of water by water consumed. The answer is the duration the water will last.
FAQs
How can the capacity of a water tank be determined?
1.Obtain the tank’s inner radius and height. 2.After squaring the radius, multiply by pi (3.14159…). You will now get the water tank area. 3.Multiply the result by the height to find the volume of the tank.
How long does water hold in a tank last?
It will depend on the amount of water you have saved as well as the pace at which it is flowing out. Use the tank volume calculation tool available to determine the capacity of your water storage container. 1.Find out how much it is in litres. 2.Find out how many litres of water are consumed daily. 3.Divide the total quantity of water you have by the amount of water consumption. The number of water days that you have left is the outcome.
Why is it more desirable to use cylindrical water tanks as opposed to square ones?
Tanks that are cylindrical rather than rectangular are more effective at withstanding tension. As a result, the amount of material that is needed to construct it is reduced. Cleaning rectangular tanks, particularly the corners of such tanks, is also a more challenging task.
