This article covers **5 free online horizontal cylindrical tank volume calculator websites**. These sites help you **calculate volume of liquid in the tank based on tank diameter, length, liquid height**, etc. You just need to provide these input values and the results will be in front of you.

Some of these horizontal cylindrical tank volume calculators provide a dummy image or **tank diagram** (including filled liquid) based on the input items and output results. A few unique features are also available. For example, you can **add rows and columns to get results for different tank length, height**, etc., **save calculations online to use the same calculations again, view a meter that shows available liquid**, etc.

Let’s check these free online horizontal cylindrical tank volume calculators one by one.

## Handymath.com

**Handymath.com** website brings a very simple and useful horizontal cylindrical tank volume calculator. Its link is here. It also provides a dummy diagram to see height, diameter, and length of tanker. The interface is user-friendly. There are two sections:

- One section is there to enter diameter of cylinder, length of cylinder, and height of liquid cylinder. The values can be added in ft, m, cm, or in. You can set different value type (inches for one, cm for another, etc.) for each item.
- Another section helps to set output type (gallon, litre, ft, in, cm, etc.) for volume of liquid in cylinder.

You can also add more rows and columns for these sections to calculate output for multiple tanks and get the output according to the input data and rows and columns.

When the details are added, calculate the output and you will come to know about volume of liquid in cylinder.

## Blocklayer

**Blocklayer** brings an advanced horizontal cylindrical tank volume calculator. You can access that calculator using this link. It lets you perform calculation as well as save the calculation online for later use. Another unique feature of this website is it also lets you check estimation time to fill the total tank and current time to empty the tank. So, start adding input details and get the output. You can:

- Set the end types for tank: hemispherical ends, flat ends, or ellipsoidal ends.
- Add values for tank diameter in inches or feet.
- Set fill rate.
- Add tank length.
- Add filled to depth value, etc.

Based on the input values, it generates a meter and shows how much liquid is remaining (in US gallons) and total liquid capacity.

A diagram is also generated which shows tank length, height, total fill, and filled liquid in the tank. You will also be able change fill level using the available slider.

## Horizontal Storage Tank Volume Calculator

**Horizontal Storage Tank Volume Calculator** (Homepage) has a beautiful interface where you can add input values and get the results. Like Blocklayer website, it also provides a meter which shows remaining liquid (in percentage).

You can set measurement type (inches or metric), tank diameter, dip level, and tank length. Enter values and the results are visible on the right side. You will see current capacity and maximum capacity of liquid in the tank in litres, gallons (US and UK), cubic foot, etc.

## Calculatorsoup.com

Calculatorsoup website brings a simple horizontal cylinder tank volume calculator where you can check total volume of liquid and filled volume of liquid in the tank. The result is provided in gallons (US). A dummy image showing the length, diameter, and liquid height is also provided by it.

Once you have entered the tank length, filled depth (in feet), and tank diameter, the result will is visible in a separate box instantly. You can also share your answer using the available link which is a nice feature.

## Tank Volume Calculator

**Tank Volume Calculator** (Homepage) is a very simple website but gives very good results. You can enter tank diameter, length, and oil/water or some other liquid height (optional) and then you can get the results.

The result provides tank capacity in different measurements which include liters, M3, cubit foot, gallons (US), gallons (UK), etc. It also provides a basic diagram and shows liquid height in the tank based on the input value which gives a good idea about tank capacity and liquid height in the tank.

### The Conclusion:

Here I close this list which has very good online horizontal cylindrical tank volume calculator websites. Since the output comes as expected in all the sites, so you can try any of these free websites. My favorite website on this list is “Handymath.com” because it lets you calculate results for different tank length, liquid height, and tank diameter in one go.
