Wood density, also referred to as bulk density or weight density, is a measurement of weight per unit volume. Wood density varies among different tree species and even within the same species. The amount of moisture in the wood can affect the density. Therefore, measurements are given for wood that is seasoned, or completely dried, before being measured.
