Methodology

Cardboard density and calculation basis

Evidence status: needs-review.

Paper and board density requires a stated product structure and thickness convention.

method: Separate apparent sheet and apparent bulk density conventions

Source basis: ISO, ISO 534:2011 — Paper and board: thickness, density and specific volume. Public standard scope. https://www.iso.org/standard/53060.html Applicability: context-only.

Identify product and applicable apparent-density method.

ISO 534 excludes corrugated fibreboard; the bulk method is unsuitable for board.

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 21.911118 fl oz (US) per lb.

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