Specific Gravity

Specific gravity is a simple ratio between the weight of wood and the weight of water. For instance, the typical dried weight of a cubic-foot of Hard Maple is 45 lbs. and the weight of a cubic foot of water is 62.38 lbs. To calculate specific gravity, divide 45 by 62.38 = .72

Substances with a SG of less than one will float.
