The diameter measuring tape enables the quick and easy calculation of tree diameters. The tape is printed with special graduations that convert a measure of circumference into its associated diameter. Graduations are available in imperial or metric and are normally rounded down to the nearest whole unit.
To use, simply wrap around the stem of the tree at the height you require and read off the value in a conventional manner. The indicated value is treated as the stem diameter.
Available in both metric and imperial
