Just divide the circumference by π to find the diameter. For example, if your circle has a circumference of 23 inches, the diameter would be 23/π, or approximately 7.32 inches. If you only know the area of the circle, use the formula diameter = 2 x √(area/π).
Are trees measured in diameter or circumference?
The national scoring system for big trees has always utilized circumference rather than diameter. Height is measured from ground level, on the uphill side of the tree, to the tip of the tree's tallest leader. A height measurement is best obtained by using forestry instruments such as a clino- meter or relaskop.

How can you measure the height of a tree without a tape measure?
The stick is held pointing straight up, at 90 degrees to your outstretched, straight arm. Carefully walk backwards until the top of the tree lines up with the top of your stick. Mark where your feet are. The distance between your feet and the tree is roughly equivalent to the height of the tree.

What is used to measure the height of a tree?
Electronic hypsometers (or “lasers”) are very easy to use, and are becoming the standard instrument for measuring trees in most areas. They come with a variety of different complexities and capabilities, but essentially, they work the same as a clinometer.
How to measure the diameter of a tree?
Measure 4.5 feet up the trunk of the tree to locate the point at which to measure the tree's diameter. If the tree trunk splits below this height, the two separate trunks are considered, for most purposes, to be separate trees and are measured as such. If a branch occurs at this height, take the diameter either a foot below the branch or above the branch where the swelling around the branch junction no longer exists.

What is the best instrument to measure a tree?
Steel diameter tapes and Biltmore sticks are standard instruments used in forestry that simplify the diameter-calculating process, but a cloth tape measure and a simple calculation suffice for measuring a tree in your yard, woods or neighborhood park.
How far up the side of a tree should you measure?
When trees are leaning, measure the circumference 4.5 feet up the side of the trunk in the direction of the lean. For trees growing on a slope, measure 4.5 feet from the upper side of the slope.
How to classify a tree?
While a tree's diameter is usually calculated to the nearest 1/10 of an inch, diameters are usually grouped into 1-inch classes.

How to determine the size of a multi-stemmed tree?
For multi-stemmed trees, the size is determined by measuring all the trunks, and then adding the total diameter of the largest trunk to one-half the diameter of each additional trunk (see Figure 80-7). A multi-stemmed tree has trunks that are connected above the ground and does not include individual trees growing close together or from a common rootstock that do not have trunks connected above the ground.

Why is it important to note that the data provided in the table is more precise for trees that are grown in a?
Note: It is important to note that the data provided in the table is more precise for trees that are grown in a forest environment as these are typically thinner than those found in open conditions. Trees that are in urban environments tend to suffer from being exposed to stressors such as pollution, inhibited growing areas, and damage.

How far from the ground should I run a measuring tape around a tree?
First we took a measuring tape and ran it around the tree at least 4.5′ feet from the ground. Note that there are many factors that may contribute to the size of a tree other than age; i.e. the tree may have had major competition, the soil may have been extremely fertile or really crappy, all will contribute to the trees growth.
