Input the diameter of the cylinder.

The diameter should represent the full width of the tank from one side to the other.


Step 3: Enter Height or Length

For a vertical tank:

  • Enter the tank height.

For a horizontal tank:

  • Enter the tank length.

Step 4: Choose a Unit

Select the measurement unit used for your dimensions:

  • Inches
  • Feet
  • Centimeters
  • Meters

The calculator automatically converts the measurements internally.


Step 5: Click Calculate

Press the Calculate button to generate results instantly.


Step 6: Review Results

The calculator displays:

  • Volume in Cubic Feet
  • Capacity in US Gallons
  • Capacity in Liters
  • Water Weight in Pounds

Step 7: Copy or Share Results

Use the built-in options to:

  • Copy the results
  • Share the tank capacity information

This is particularly useful for project documentation and communication.


Practical Example 1: Water Storage Tank

Imagine you own a farm and use a vertical water storage tank.

Tank specifications:

  • Diameter: 6 feet
  • Height: 10 feet

After entering the values into the calculator, you instantly receive:

  • Total tank volume
  • Gallon capacity
  • Liter capacity
  • Estimated water weight

This information helps determine:

  • How much water can be stored
  • Irrigation scheduling
  • Water transportation planning

Practical Example 2: Horizontal Fuel Tank

Suppose you have a horizontal fuel tank for equipment storage.

Tank dimensions:

  • Diameter: 4 feet
  • Length: 12 feet

Using the calculator allows you to quickly determine:

  • Maximum fuel capacity
  • Storage requirements
  • Refill schedules
  • Transportation considerations

Instead of performing multiple manual calculations, everything is calculated instantly.
