Cast Iron density and calculation basis
Cast Iron is represented in this table by a fixed reference density of 7200 kg/m^3, equivalent to 7.2 g/cm^3. Representative cast iron density.
At this fixed reference, 1 liter of Cast Iron corresponds to 7.2 kg, while 1 kg corresponds to 0.138889 liters. Its table density is 622.2% higher than the 997 kg/m^3 water reference used in this dataset.
Among the 13 fixed table records labeled Metals, the nearest density to Cast Iron is Zinc at 7140 kg/m^3: an absolute difference of 60 kg/m^3 (0.8% relative to Cast Iron). 3 records have a lower fixed density and 9 have a higher one. The observed range in this labeled group is Aluminum at 2700 kg/m^3 to Gold at 19320 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 3.755432 lb 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.
