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

V = π(D/2)² × H. ×1000 converts m³ to liters. For US gallons, divide by 3.785; for barrels divide by 159.

Introduction

Calculate tank capacity in liters and convert to US gallons (÷3.785), imperial gallons (÷4.546), and oil barrels (÷159). Supports any cylindrical tank.

How This Calculator Works

V = π(D/2)² × H. ×1000 converts m³ to liters. For US gallons, divide by 3.785; for barrels divide by 159.

Step-by-step process:

  1. Enter your input values in the calculator above
  2. The engine converts all inputs to SI base units (meters, kg, Pa)
  3. The formula is evaluated: pi * (diameter/2)^2 * height * 1000
  4. Result is formatted with the appropriate unit and precision

Calculation Example

3m × 6m tank = 42,412 L = 11,205 US gal = 9,329 imperial gal = 267 barrels.

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

Engineering Applications

  • •Tank farm design
  • •Oil storage
  • •Bulk liquid handling
  • •Shipping volume calculation

Frequently Asked Questions

How do I convert to barrels of oil?

1 barrel = 159 liters = 42 US gallons. Divide liters by 159.

What is the difference between US and imperial gallons?

1 US gallon = 3.785 L; 1 imperial (UK) gallon = 4.546 L. US gallons are ~20% smaller.

How do I convert capacity between liters and cubic meters?

1 m³ = 1000 L. For example, 10 m³ = 10,000 L. Multiply m³ by 1000 to get liters, or divide liters by 1000 to get m³.
