7. Diameter tape - Wikipedia

   en.wikipedia.org/wiki/Diameter_tape

   To measure the diameter of a tree, the diameter tape (diameter side facing user) is wrapped around the tree, in the plane perpendicular to the axis of the trunk at 4.5 feet (1.4 m) above ground (or 4.27 feet (1.30 m), depending on the location) . Where the number "0" aligns with the rest of the tape, the diameter can be read directly from the ...
