Enter diameter, length, and fill level, then click Calculate Volume.

This calculator determines the volume of liquid in a horizontal cylindrical tank based on the fill level. It uses the segment area formula: A = r²/2 × (θ — sin(θ)), where θ = 2·arccos((r—h)/r), r is the tank radius, and h is the liquid height. The total volume is then V = A × L, where L is the tank length. This is essential for fuel storage, water tanks, chemical processing, and industrial applications. The calculator provides results in cubic meters, liters, and US gallons. Understanding liquid volume by fill level helps in inventory management, consumption tracking, and tank capacity planning.

1. Enter the Diameter of the horizontal cylindrical tank.
2. Enter the Length of the tank.
3. Enter the Fill Level in meters OR as a percentage.
4. If both are entered, percentage takes priority.
5. Click Calculate Volume to compute the liquid volume.
6. The result shows volume in m³, liters, US gallons, and tank capacity.
7. Click Reset to restore default example values.
