Determining the specific gravity of wood

A method of ascertaining the specific gravity of wood is to submerge the wooden billet in water and divide the length of the submerged part by the total length of the billet.

Alternatively, you can use the widget below to calculate the specific gravity for you. Be sure to measure the dimensions and weight as precisely as possible. Typical results range from 0.38 - 0.45 for spruce and 0.50 - 0.60 for maple.

The dimensions are input in millimeters, the weight in grams. The widget first calculates the surface = ((a+c)/2)*b, then the volume = ((surface+surface)/2)*d and finally specific gravity = weight/volume.

I wood density of about 0.75.Do I use wood that is suitable for making violin?
please guide me....

Hello, for spruce that would be very heavy /numbers around .40 are often considered ideal/, for maple it would be somewhat usable /.55 often considered ideal/.

Wouldn't the moisture content of the wood factor in here?

Yes, it would - a bit. In the grand scheme of things, who cares, really
