Converting Factors and Tables of Equivalents Used in Forestry
註釋The purpose of this handbook is to provide members of the Forest Service with conversion factors and forest measurements that are more or less frequently encountered in forest literature. These are expressed in tabular form where it appears most advantageous to do so; in the other cases a series of alignment charts have been prepared, which permit the direct determination of values in multiple form. There are included also certain other tables giving data more or less commonly used in forest calculations.
