Specific gravity.
Void ratio is defined as the ratio of the volume of the void space compared to the volume of the solid particles.
I am looking for the formula to figure strength to weight ratio for a dome that I built for a project
Packing factor is a dimensionless ratio that describes the amount of volume that a substance takes up in a particular volume. For example, if you have a box and you fill it with balls, the volume of the box is taken up by the balls and by the space in between the balls. The packing factor would be (volume of the balls)/(volume of the box). Packing factor is, among other things, relevant to the arrangement of atoms in different crystallographic structures.
You need to calculate the total volume of the space that the concrete has to fill. if you're doing a slab 4" thick a cu. yd. will cover 81 sq. ft. Take the total area and divide by 81 to get the number of yard needed.
The compression ratio of an internal-combustion engine, or an IC engine as it is more commonly called, is the ratio of the volume the highest capacity of the combustion chamber to its lowest capacity. In the IC engine, the piston makes a stroke, resulting in the compression of the air in the combustion chamber - the ratio between the volume of the cylinder and combustion chamber when the piston is at the bottom of its stroke, and the volume of the combustion chamber when the piston is at the top of its stroke, is the compression ratio.
This ratio is called the specific gravity.
Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water.

Density is the ratio of the mass of a substance to the volume of the substance.
Without knowing the weight to volume ratio of the item in question, there is no way to convert the weight to a volume.
