Plywood

==Sizes==
The most commonly used thickness range is from {{convert|1/8|to|3.0|in|mm}}. The sizes of the most commonly used plywood sheets are 4 x 8 feet (1220 x 2440&nbsp;mm)<ref>{{Cite web|url=https://goldwoodply.com/goldwood.php|title=Mr Plywood India: Mr Plywood Yamunanagar, Mr Grade Plywood Manufacturers in Yamuna Nagar, India}}</ref> which was first used by the Portland Manufacturing Company, who developed what we know of as modern veneer core plywood for the 1905 Portland World Fair. A common metric size for a sheet of plywood is 1200 x 2400&nbsp;mm. {{convert|5|xx|5|ft|mm}} is also a common European size for Baltic birch ply, and aircraft ply.<ref>[http://www.cps.gov.on.ca/english/plans/E9000/9011/M-9011L.pdf Metric conversions, Canadian government publication] {{webarchive|url=https://web.archive.org/web/20100216044053/http://www.cps.gov.on.ca/english/plans/E9000/9011/M-9011L.pdf |date=2010-02-16 }}.

Sizes on specialised plywood for concrete-forming can range from {{convert|abbr=on|15/64|to|13/16|in|mm|0}}, and a multitude of formats exist, though 15&nbsp;×&nbsp;{{convert|abbr=on|750|xx|1,500|mm|in|disp=x| (.59in&nbsp;×&nbsp;|)}} (19/32in&nbsp;×&nbsp;2&nbsp;ft-6in&nbsp;×&nbsp;4&nbsp;ft-11in)<!--todo: replace with convert template once it supports fractional ft-inch output in ranges--> is very commonly used.

Aircraft plywood is available in thicknesses of {{convert|1/8|in|mm|0}} (3 ply construction) and upwards; typically aircraft plywood uses veneers of 0.5&nbsp;mm&nbsp;(approx&nbsp;1/64&nbsp;in) thickness although much thinner veneers such as 0.1&nbsp;mm are also used in construction of some of the thinner panels.
