Enter the radius and height into the calculator to determine the barrel capacity. This calculator can also evaluate any of the variables given the others are known.

## Barrel Capacity Formula

The following formula is used to calculate the capacity of a barrel.

BC = π * r² * h

Variables:

• BC is the barrel capacity (liters or gallons)
• π is a constant, approximately 3.14159
• r is the radius of the barrel (meters or feet)
• h is the height of the barrel (meters or feet)

To calculate the barrel capacity, square the radius of the barrel and multiply it by the constant π. Then, multiply the result by the height of the barrel. The result will be the volume or capacity of the barrel.

## What is a Barrel Capacity?

A barrel capacity refers to the volume that a barrel can hold. It is often used as a unit of measurement in the oil industry, where one barrel is equivalent to 42 US gallons or approximately 159 liters. The term is also used in other industries such as beer and wine production, where the size of a barrel can vary. The capacity of a barrel can influence the quantity of production, storage, and transportation of goods.

## How to Calculate Barrel Capacity?

The following steps outline how to calculate the Barrel Capacity.

1. First, determine the radius of the barrel (r) in meters or feet.
2. Next, determine the height of the barrel (h) in meters or feet.
3. Next, gather the formula from above = BC = π * r² * h.
4. Finally, calculate the Barrel Capacity.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

radius of the barrel (r) = 2 meters

height of the barrel (h) = 5 meters
