Methodology

Cast Iron density and calculation basis

Evidence status: publishable.

Representative gray cast iron density; ductile iron and other grades differ.

grade: Dura-Bar gray cast iron

Source basis: Dura-Bar, Density technical brief, 02/2019. Technical brief: gray iron versus ductile iron density. https://www.dura-bar.com/getmedia/811341e6-6541-48f9-b719-1d1d666a2bc8/dura-bar-density-0219.pdf?ext=.pdf Applicability: adopted-context.

Ductile iron has a separate 0.255 lb/in³ value; temperature not stated.

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 0.036691 gal (US) per kg.

Use a measured density for a specific batch, grade or supplier; the table value is a reference, not a product specification.
