The variation of wood density and moisture within boles of trees has been the sub-ject of numerous investigations (Clark and Gibbs 1957, Markstrom and Hann 1972, Parker 1954, Stewart 1967) that were viewed as academic exercises with limited in-terest and application. This view, however, has changed.

Specific Gravity of Wood Database * Wagner Meters

So as the volume of the wood sample shrinks, the density (SG) of the wood increases because the formula for the wood density is the weight of the wood sample divided by the volume of the wood sample, or more simply the ratio of the weight of the wood to its volume. As the weight stays the same during shrinkage, the volume decreases.

Wood Strengths - WoodWorkWeb

For wood, density is expressed as pounds per cubic foot, kilograms per cubic meter, or grams per cubic centimeter - at a specified moisture content. Density is the single most important indicator of strength in wood: a wood that is heavier (i.e., more wood substance per unit volume) will generally tend to be stronger than a lighter one.

The Importance of Wood Density (Specific Gravity) and Its ...

Wood density and wood specific gravity both indicate the amount of actual wood substance present in a unit volume of wood (see Chap. 1.3.1). Although there are several different methods used to measure wood density, the standard way is to calculate the ratio between the dry weight of wood divided by the green volume of the same wood.
