What is a Cylinder Tank Capacity Calculator?
A Cylinder Tank Capacity Calculator is a tool used to determine the total volume or storage capacity of a cylindrical tank. These tanks are commonly used to store liquids like water, fuel, chemicals, and gases. The calculator helps figure out how much the tank can hold based on its dimensions — specifically its radius (or diameter) and height.

Why use a Cylinder Tank Capacity Calculator?

  • Accurate storage measurement: Ensures you know the exact capacity of a tank for proper storage and safety.
  • Inventory and supply management: Helps manage liquid levels and prevent overfilling or underfilling.
  • Engineering and construction: Assists in designing tanks with the right size for specific needs.
  • Cost estimation: Knowing the capacity helps estimate costs for filling the tank with liquids or gases.
  • Compliance: Helps meet safety and regulatory standards for liquid storage.

How does a Cylinder Tank Capacity Calculator work?
The calculator uses the formula for the volume of a cylinder:

V = πr²h

Where:

  • V = Volume of the tank (capacity)
  • r = Radius of the circular base of the tank
  • h = Height of the tank
  • π ≈ 3.14159

Steps to calculate capacity:

  1. Measure the radius: Half the diameter of the tank’s circular base.
  2. Measure the height: Distance from the base to the top of the tank.
  3. Square the radius: Multiply the radius by itself (r²).
  4. Multiply by π\pi π: Use the value of pi for precision.
  5. Multiply by the height: V = πr²h gives the tank’s total capacity.

For horizontal tanks: If the tank lies on its side, you might also need to calculate the filled volume based on liquid level — this requires more advanced formulas.

Example Calculation:
For a vertical cylindrical water tank with:

  • Radius = 2 meters
  • Height = 5 meters
V = π × 2² × 5 = π × 4 × 5 = 20π ≈ 62.83 m³

The capacity of the tank is approximately 62.83 cubic meters, or 62,830 liters (since 1 m³ = 1000 liters).

When is it used?

  • Agriculture: Measuring water capacity for irrigation tanks.
  • Industrial settings: Storing chemicals or fuels.
  • Residential: Estimating home water tank capacity.
  • Emergency preparedness: Planning water storage.
  • Transport: Calculating capacity of cylindrical tanker trucks or railcars.
