Spectra Did you know what would happen to the sound of the violin if we remove all higher harmonics from it leaving only the main frequency? More about Lumber Volume Measures. BC is the usable height of the tree — anything above point C will be discarded. This height equals the tangent of the angle A multiplied by AB.
A hypsometer allows the user to calculate the height of an object by providing the value for the height above the eye level, height A, and the height below the eye level, height B. The two are then added together. How the logs would be cut depends on the specific needs of the buyer.
The tree on the left is cut into two logs, A and B, while the tree on the right is cut into a single log C. The total volume of logs A and B is larger than that of log C, but log C is longer, which is beneficial in some cases. Bark and wood that are discarded are labeled in brown and pink. Within the allowed diameter of the smallest width at the top of the log, marked in blue, a log can be cut into boards in a variety of ways.
The rectangles in different shades of yellow mark possible cuts for boards in cross-section. Pink and brown sections are the discarded wood and bark respectively.

Description of metric prefixes and molar mass of compounds calculator. Lumber Volume Measures Converter Lumber also known as timber is wood in any of its stages from felling to readiness for use as the structural material for construction or wood pulp for paper production. Using the Lumber Volume Measures Converter Converter This online unit converter allows quick and accurate conversion between many units of measure, from one system to another.
Measuring Volume of Growing Trees When estimating the volume of lumber from the trees that are still growing, one can collect measurements of a sample plot, and then approximate these calculations for the entire plot. Determining Height First, it is important to determine which part of the tree can be used commercially, and which part is to be discarded.
Determining the Diameter and Calculating Volume Once the height is known, the diameter of the tree is measured. Measuring Lumber There are many different units for measuring the volume of lumber — the choice depends on the intended use of the lumber and the length of each piece of wood.
Lumber Dimensions One could calculate the volume of lumber cut into boards by multiplying their width by the height and by the length. Board Foot Within the allowed diameter of the smallest width at the top of the log, marked in blue, a log can be cut into boards in a variety of ways. Two cords of firewood Cords Unprocessed wood used for firewood or production of paper, which is stacked together is measured in cords.
Cubic Feet or Meters Unlike board feet, cubic feet or cubic meters are often used to measure entire logs including the parts that will later be discarded during processing, but excluding space between the logs if they are stacked, and often excluding the volume of the bark. It is defined as the volume of a cube with edges one foot in length. The board-foot is a specialized unit of volume for measuring lumber in the United States and Canada. Unfortunately, it is not truly a measure of volume, due to nominal and actual measures used in the lumber business.
In addition, the definition is different for hardwood and softwood. Note that the cf of a 2x6x18' board is 1. The calculations here do not apply to nominal lumber sizes which are actually slightly less.
