The following appendix have been developed to support Lasting Forests.

While many units of measure have become widely accepted, almost standard, there are often needs to transform measures from the literature into relationships among various parts of the land use and management system. Advice is sought on other measurements and coefficients that are useful and should be added to this table.

Multiply the unit in the left column by the number shown in the center to get the value desired in the right column
