CORDWOOD WEIGHT CONVERSION FACTORS
Weight conversion factors are generally established by the various mills and are accepted for billing purposes. The following weight conversion factors may be used as guidelines in the conversion of weight scale to standard 128 cubic foot cord.
Weights shown are for average cordwood size wood that is reasonably straight. Consequently, wood conditions which may increase or decrease the amount of solid wood in a cord must be taken into consideration when applying these data.
Up to a 5% reduction is often warranted for wood that is unusually small, or wood that is usually crooked.
Up to a 5% increase is often warranted if sawlog size material was cut for pulp, or the material is exceptionally straight.
Seasoned wood is normally understood to be that which was cut and dried two or more months between April 1 and October 31 before weighing. All other wood should be considered green.
Factors for mixed cordwood may be developed by weighted average of cruise estimates based on species volume distribution and/or ocular estimate.
