In practical terms, the number itself isn't all that meaningful, but it becomes useful to use in comparison with other woods. For instance, Ipe is known to have excellent strength properties among imported species, and has a crushing strength of 13,510 lb f /in 2 (93.1 MPa). In comparison, White Oak is a well-known wood used in cabinetry and furniture, …
