Vibration Engineering WebSimply enter the density of the material in which your are interested, select the shape from the drop-down list, enter the dimensions, then hit the Calculate button. Water's weight is one gram per cubic centimeter - a material with, for example, 1.5 specific density would then weigh 1.5 grams per cubic centimeter. To figure the specific gravity of a substance take the number of pounds per gallon the substance weighs and divide it by 8. The tests for density and SG are particularly significant in the custom sheet industry because plastic sheet is sold on a cost per pound basis. At Plastics For Change, we are giving second life to discarded plastic numbers 1,2,4, and 5 and re-use them for the creation of various different products while cleaning our oceans!

These specialty materials have densities of up to 15 g/cc yet still have the moldability of plastics. Density refers to the mass per unit volume of a material, whereas SG refers to a measure of the ratio of mass of a given volume of material at 23C to the same volume of deionized water. Some manufacturers may consider testing and certification an obstacle to overcome to get to market. the molded piece as compared to the weight of an equal volume of water Therefore, the specific gravity is a unitless number.
