Joe_Carrick Posted August 7, 2015 Share Posted August 7, 2015 For you metric users, I have a question about how areas are generally indicated on your projects for various components. 1. Site, Rooms, etc in Sq.Meters(sq.m.)? 2. Doors, Windows, Counter tops in Sq.Centimeters (sq.cm.)? 3. Other items ? 4. Is anything (such as cross sectional area of framing members, etc) in sq.mm. ? IOW, what are the standards? For Imperial projects we use a combination of Sq.Ft. and Sq.In. My guess is that metric would generally use Sq.M. ad Sq.Cm. but I really don't want to guess.

glennw Posted August 8, 2015 Share Posted August 8, 2015 Joe, We usually use m² for site and floor areas. Same for counter tops, windows, doors, etc - this format can cover a huge range of areas. We may see sq m sometimes, but I try to avoid that. If a property is very large, we will use hectares. (1 hectare = 10,000 m²). It is not usual to call up cross section areas for framing members, but if the area were very small, we would use mm² - I don't think I have ever used this. We never use square or lineal centimeters.

Joe_Carrick Posted August 8, 2015 Author Share Posted August 8, 2015 Thanks Glenn, I have bee working on some Macro Packages for Area Analysis [building, Site, Openings (Doors & Windows), Vents] and also a basic structural member sizing package] which I want to make sure works for both Imperial and Metric. Based on your input, I will make most things in sq.m. Thanks Link to comment Share on other sites More sharing options...
glennw Posted August 8, 2015 Share Posted August 8, 2015 Based on your input, I will make most things in sq.m. Joe, I hope you are going to do it in m² and not as sq m. Link to comment Share on other sites More sharing options...

Joe_Carrick Posted August 11, 2015 Author Share Posted August 11, 2015 Some more questions: In the USA & Canada most building products are Imperial units (ie: 48"x 96" Sheet Goods, 2x4 (1.5" x 3.5") Lumber, etc. These are not round numbers in metric so I would assume that outside of North America those materials come in different sizes. What are the common sizes in Australia, Europe, etc? Link to comment Share on other sites More sharing options...
Joe_Carrick Posted August 11, 2015 Author Share Posted August 11, 2015 I see on the web that Australian sheets of particle board are 1200x2400 (slightly smaller than North American). So that would match up with framing spacing, etc. Link to comment Share on other sites More sharing options...
Kiwideziner Posted August 11, 2015 Share Posted August 11, 2015 Joe Gib (sheetrock) 1200mm or 1350mm wide x various lenghts ie 2400,3000,3600,4200,6000. Other products -ply 1200x 2400mm or 2750mm - MDF flooring 1800mmx3600mm - Hardies sheets 1200X2400mm or 2700mm framing timber typically 45 wide x 90,140,190,240,290mm deep Link to comment Share on other sites More sharing options...
Kiwideziner Posted August 11, 2015 Share Posted August 11, 2015 We used to have particle board 8 foot x 4 foot then it became 2440mm x1220mm then we went fully metric and it was rounded to 2400x1200 Link to comment Share on other sites More sharing options...
Kiwideziner Posted August 11, 2015 Share Posted August 11, 2015 frame centres typically 600 for std single story but varies for wind zones and earthquakes and stud height to 400mm or 300mm Link to comment Share on other sites More sharing options...
Joe_Carrick Posted August 11, 2015 Author Share Posted August 11, 2015 Thanks Graeme. I really appreciate the info. I notice that all of those are mm which I believe is the standard for linear measurements but for areas it's m2. Is there a cut off point where area is cm2 or mm2?

Kiwideziner Posted August 11, 2015 Share Posted August 11, 2015 Joe We DO NOT use cm for anything. cm is a non standard ISO unit. mm² is only used for gutter cross section area and similar that I can think of off hand cheers Link to comment Share on other sites More sharing options...
