Plastic (HDPE) density and calculation basis
Plastic (HDPE) is represented in this table by a fixed reference density of 950 kg/m^3, equivalent to 0.95 g/cm^3. Typical high-density polyethylene density.
At this fixed reference, 1 liter of Plastic (HDPE) corresponds to 0.95 kg, while 1 kg corresponds to 1.052632 liters. Its table density is 4.7% lower than the 997 kg/m^3 water reference used in this dataset.
Among the 4 fixed table records labeled Polymers, the nearest density to Plastic (HDPE) is Rubber (Solid) at 1100 kg/m^3: an absolute difference of 150 kg/m^3 (15.8% relative to Plastic (HDPE)). 0 records have a lower fixed density and 3 have a higher one. The observed range in this labeled group is Plastic (HDPE) at 950 kg/m^3 to Plastic (PVC) at 1380 kg/m^3. This is a numerical comparison, not a claim that the materials are interchangeable.
For this direction, mass is calculated as volume multiplied by density after normalizing the units to cubic meters and kilograms. The resulting page multiplier is 3.596141 kg per gal (US).
The fixed value supports repeatable calculations but is not a batch, grade, supplier, or laboratory specification. Use a measured or certified density when those conditions control the result.
