Methodology
Glass density and calculation basis
Evidence status: publishable.
Reference density for soda-lime-silica float glass; other glass compositions differ.
composition: Soda-lime-silica float glass
Source basis: Pilkington, ATS-129: Properties of Soda-Lime-Silica Float Glass, 04/2025. ATS-129, PDF p.2, density entry. https://www.pilkington.com/-/media/pilkington/site-content/usa/window-manufacturers/technical-bulletins/ats-129---properties-of-soda-lime-silica-float-glass.pdf Applicability: adopted-context.
Density temperature not specified; temperatures on thermal properties do not apply to this entry.
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 20.863511 oz per cup (US).
Use a measured density for a specific batch, grade or supplier; the table value is a reference, not a product specification.
