Full API documentation

Explanation

Pounds of Cast Iron convert to us fluid ounces using one fixed density basis of 7200 kg/m^3. The same density model is used in the calculator, common values, and mirror route so storage, batching, and material-planning checks stay aligned.

Representative cast iron density.

Material & Method

Material used: Cast Iron. Method basis: density fixed at 7,200 kg/m^3 for every calculation on this page.
Applied relationship: 1 Pound (mass) = 2.130248 US Fluid Ounces (volume) using the same material density basis.
Reference rule: snapshot, calculator, and common values table use the same material basis throughout the page.

Methodology

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, volume is calculated as mass divided by density after normalizing the units to kilograms and cubic meters. The resulting page multiplier is 2.130248 fl oz (US) per lb.

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.
