Until early in the 20th century, it was the unit used to measure the depth of mines (mineral extraction) in the United Kingdom. [30] Miners also use it as a unit of area equal to 6 feet square (3.34 m 2) in the plane of a vein. [2] In Britain, it can mean the quantity of wood in a pile of any length measuring 6 feet (1.8 m) square in cross ...
There are 7 other coastal redwoods known to be over 112 meters (367 feet) in height, and 222 specimens over 105 meters (344 feet). [7] There are only five species known to grow over 91 meters (299 feet) in height worldwide. [8] There are historical accounts of extremely tall and large trees.
A volume table is a chart to aid in the estimation of standing timber volume. These tables are based on volume equations and use correlations between certain aspects of a tree to estimate the volume to a degree of certainty. The diameter at breast height (DBH) and the merchantable height are used to determine the total volume. Difficulties ...
A face cord is an informal measurement for stacked firewood, [1] sometimes called a rick. [2] Width and height is typically the same as a cord (3.6 m 3), but the depth can vary. [3] The front face is the same as a cord 4 by 8 feet (1.2 by 2.4 m), hence the name. The depth is generally 16 inches (410 mm) (for use in residential fireplaces) but ...
A cord is the amount of wood that, when "racked and well stowed" (arranged so pieces are aligned, parallel, touching, and compact), occupies a volume of 128 cubic feet (3.62 m 3). [1] This corresponds to a well-stacked woodpile 4 feet (122 cm) high, 8 feet (244 cm) wide, and 4 feet (122 cm) deep; or any other arrangement of linear measurements ...
In this case a better option would be to measure the standard girth measurement at 4.5 feet above ground level on the high side of the tree and note this in the measurement description. If measuring a mountaintop forest of stunted trees only six feet tall, a girth measurement made at 4.5 feet would be meaningless.
[1] [2] When taking forest inventory the following are important things to measure and note: species, diameter at breast height (DBH), height, site quality, age, and defects. From the data collected one can calculate the number of trees per acre, the basal area, the volume of trees in an area, and the value of the timber. Inventories can be ...
As well, lumber is still measured in Costa Rica using a system based on 4 vara, or 11 feet, for both round and square wood. With square wood, using inches, the width is multiplied by the depth to get a measurement called pulgadas, or inches. The lumber is charged 'per inch', which is a measurement of 2.2 litres (11 ⁄ 12 board foot).
