Cylinder Volume Calculator

Calculate the volume of a cylinder in liters, m³, or gallons from diameter and height.

Formula
π × (diameter ÷ 2)² × height × 1000
Result unit: L

V = π(D/2)² × H. Dimensions in m after conversion; ×1000 converts m³ to liters.

Introduction

Calculate the internal volume of a cylinder — the basis for tank volume, pipe capacity, and pressure vessel calculations. For horizontal tanks, use the tank volume calculator for partially-filled volumes.

Calculation Example

3m diameter × 6m tall cylinder = 42,412 liters (same as our vertical tank example).

Inputs: diameter=3, height=6
Result: 42412 L

Engineering Applications

  • •Tank capacity
  • •Pipe volume
  • •Vessel sizing
  • •Receiver tank design

Frequently Asked Questions

How do I convert liters to gallons?

1 liter = 0.264 US gallons = 0.22 UK gallons. Divide liters by 3.785 for US gallons.

Does this work for horizontal tanks?

This gives total (100% full) volume. For partially-filled horizontal tanks, use the liquid-volume calculator which accounts for fill height.
