A good indicator of a wood's strength is its density — the weight for a given volume. This is measured by its specific gravity — the weight of a volume of wood divided by the weight of the same volume of water. Generally, the higher the ratio, the denser and stronger the wood. This is not always the case, but specific gravity is a useful ...
