Density system unit unit-code symbol or abbrev. notes sample default conversion combination output units Metric: kilogram per cubic metre: kg/m3 kg/m 3: 1.0 kg/m 3 (1.7 lb/cu yd)
The density is typically between 500 and 1,000 kg/m 3 (31 and 62 lb/cu ft). [5] The range of density and classification as light-, standard-, or high-density board is a misnomer and confusing. The density of the board, when evaluated in relation to the density of the fibre that goes into making the panel, is important.

Plywood and OSB typically have a density of 560–640 kg/m 3 (35–40 lb/cu ft). For example, 9.5 mm (3 ⁄ 8 in) plywood sheathing or OSB sheathing typically has a surface density of 4.9–5.9 kg/m 2 (1–1.2 lb/sq ft). [51] Many other engineered woods have densities much higher than OSB.
— "Values ranging from 21.3 to 21.5 gm/cm 3 at 20 °C have been reported for the density of annealed platinum; the best value being about 21.45 gm/cm 3 at 20 °C." 21.46 g/cm 3 — Rose, T. Kirke. The Precious Metals, Comprising Gold, Silver and Platinum .
This condition occurs when the wood is at equilibrium moisture content with air at about 65% relative humidity and temperature at 30 °C (86 °F). This density is expressed in units of kg/m 3 or lbs/ft 3.
Its wood has an average crush strength of 8,140 lb/in 2 (56.1 MPa), which exceeds many hardwoods such as white ash (7,410 lb/in 2) and black maple (6,680 lb/in 2). It is not as strong as black ironwood (9,940 lb/in 2 ), but because its average density is less than half that of ironwood, slash pine has a far greater strength-to-weight ratio.
