 # Basal Area Calculator

## Basal Area Calculator

Basal area is an area of a tree’s trunk if cut at the breast height. The basal area of a tree is calculated from its diameter at breast height (DBH). This parameter is widely used in forestry to find a tree’s age, production of oxygen, and others. Though you calculate it for a single tree, this parameter is usually used for stand density, so it’s often expressed in square meters per hectare or square feet per acre. Use the basal area calculator to find the basal area of a tree or stand density. With our calculator, you won’t have to worry about converting units or remembering formulas! You can input up to 50 DBH (diameter at breast height) values and learn the stand density in seconds!

## How to calculate basal area?

The following formula is used to calculate the basal area of a tree.

• Where BA is the basal area
• F is the foresters constant (.005454)
• DBH is the average diameter of the tree at “breast height” which is 4.5 feet (in)
• N is the number of trees per acre.

To calculate basal area, multiply the foresters constant by the average diameter of the trees at breast height squared, then multiply again by the trees per acre.

#### Example:

1. First, determine the average diameter of the trees at “breast height”.

For this example, we will say we measure 10 trees, and on average they have a diameter of 10 inches at breast height (4.5 feet).

2. Next, measure the number of trees per acre.

After counting, we find the number of trees per acre to be 250.

3. Finally, calculate the basal area.

Using the formula above, we find the basal area to be .005454*10^2*250 = 136.35 square feet per acre.

## What is a foresters constant?

The foresters constant described above is used to convert inches to square feet.
