Methodology
Plastic (PET) density and calculation basis
Plastic (PET) is represented in this table by a fixed reference density of 1370 kg/m^3, equivalent to 1.37 g/cm^3. Typical PET polymer density.
At this fixed reference, 1 liter of Plastic (PET) corresponds to 1.37 kg, while 1 kg corresponds to 0.729927 liters. Its table density is 37.4% higher 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 (PET) is Plastic (PVC) at 1380 kg/m^3: an absolute difference of 10 kg/m^3 (0.7% relative to Plastic (PET)). 2 records have a lower fixed density and 1 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 11.433204 oz per cup (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.
