WAGNER L606 - Calculating Wood Specific Gravity

38
Determining Specic Gravity
The adjustment table based on specic
gravity of solid wood is provided on the
following page. If you don’t know the
species of the wood you are using, or the
specic gravity differs from the handbook
because of a different growing region, use
the following procedure.
1. Select a sample of wood with all
edges being true. Carefully measure
the dimensions of the sample using
a caliper. You will need the length,
width, and thickness.
2. Convert these measurements to feet.
3. Carefully measure the weight of the
sample.
4. Convert the weight to pounds.
5. Calculate specic gravity.
