By default, the output value is rounded to adjust its precision to match that of the input. An input such as 1234 is interpreted as 1234 ± 0.5, while 1200 is interpreted as 1200 ± 50, and the output value is displayed accordingly, taking into account the scale factor used in the conversion.
In all cases, the data collected needs to be organized into a useful searchable format that can be used. The Native Tree Society provides a free downloadable excel spreadsheet that can be used for organizing tree datasets Tree Measurement Data Spreadsheet. [66] The spreadsheet can be modified for the needs of the user.
In antiquity, systems of measurement were defined locally: the different units might be defined independently according to the length of a king's thumb or the size of his foot, the length of stride, the length of arm, or maybe the weight of water in a keg of specific size, perhaps itself defined in hands and knuckles. The unifying ...
A hand is a unit of length used to measure the height of horses. One hand is four inches, and a value of 12.3 hands represents 12 hands + 3 inches (51 inches). Output name
Additional details on the methodology of tree height measurement, tree girth measurement, and tree volume measurement are presented in the links herein. American Forests, for example, uses a formula to calculate Big Tree Points as part of their Big Tree Program [ 3 ] that awards a tree 1 point for each foot of height, 1 point for each inch of ...
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 [13] [17] The height of this measurement point above the standard base point at midslope should also be noted. If measuring a mountaintop forest of stunted trees ...

Given the general form changes from the base to top of the tree and the pattern of change in form factor over time, a predictive model was developed and applied to a variety of trees in New England where volume estimates were made based upon measurements tree height, girth at breast height, girth at root flair, and assigned values for form ...
