If you go to a lumber yard in the USA you will purchase in board feet, and you will be given a thickness in quarters – four quarter etc…
If you walk in and say you want a one inch plank – they will sell you four quarter which will not necessarily be one inch. If you think this is weird – it is – but if you do not know the lingo you will just be treated as a newbie If you own a planer and it is big one then you can plane your own timber – fast and cheap – or they can surface it for you –slow and expensive If you need to build a 16 foot Maine lobster boat – you need 16 foot long 4 quarter planks about 5 to 8 inches wide and you will tell your students to Take the four quarter board and plane it to 10 mm thickness 10 mm is the exact thickness for white oak for steaming and bending easily – 12 mm is to thick and 9 mm is to thin I expect my students to know the hell what we are talking about John *John Nichols* Construction Science, College of Architecture | Texas A&M University ph: 979.845.6541 | [email protected] - - - - - - - - - - - - - - - - - - - - - - - - *https://nam01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.tamu.edu%2F&data=02%7C01%7Cusma%40lists.colostate.edu%7C3e59da89b67b4c60c72308d7f5f2761c%7Cafb58802ff7a4bb1ab21367ff2ecfc8b%7C0%7C0%7C637248294031412458&sdata=MByHrmELsmiIXZUwzKDP00UT22ZgCLb0asGkR479ao8%3D&reserved=0* <https://nam01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwww.tamu.edu%2F&data=02%7C01%7Cusma%40lists.colostate.edu%7C3e59da89b67b4c60c72308d7f5f2761c%7Cafb58802ff7a4bb1ab21367ff2ecfc8b%7C0%7C0%7C637248294031412458&sdata=MByHrmELsmiIXZUwzKDP00UT22ZgCLb0asGkR479ao8%3D&reserved=0> *From:* USMA <[email protected]> *On Behalf Of *Martin Vlietstra *Sent:* Monday, 11 May 2020 3:47 PM *To:* 'Al Lawrence' <[email protected]>; 'Ressel, Howard R (DOT)' < [email protected]>; 'Michael Payne' <[email protected]>; 'USMA List Server' <[email protected]> *Subject:* [USMA 1388] Re: Sent this morning to the Washington Post The use of “2 x 4” to describe timer that is 1 1/2" x 3 1/2" is a bad habit that either the UK learned from the US (or vice versa – I am not too sure which), but shortly after the UK joined the EU (or the EEC as it was), 2 x 4 timber was marketed as “95 x 47” which is what you got. *From:* USMA [mailto:[email protected] <[email protected]>] *On Behalf Of *Al Lawrence *Sent:* 11 May 2020 18:33 *To:* Ressel, Howard R (DOT); Michael Payne; USMA List Server *Subject:* [USMA 1382] Re: Sent this morning to the Washington Post Substitution is a great way to go.

Direct *conversion*, using the factors and rules of SI 10 and other sources to determine an appropriate equivalent value with an SI unit. However *substitution *a suggest a new rational metric size used for the value of the measurement for the item being converted. While conversion maintains the original standard value (rounded appropriately for accuracy and precision substitution defines a new standard value for the measurement. Substitution should not be confused with rounding. Some examples are: *Item* *Old value* *Conversion* *Substitution* Road Lane Width 12 ft 3.66 m *3.6 m* Pipe 12 in *305 mm* 300 mm Baking Temperature 450 °F 232.2 °C *230 °C* Social Distancing 6’ 1.83 m 2 m Whereas conversion will generally accommodate full compatibility between existing and new items, substitution may require modification or transitions for compatibility to occur. In the case of social distancing recommendations, international guidelines have used 2 m (I hear some countries are using 1.5 m) but CDC in the US has quoted 6’ as being an equivalent safe distance. They did not sensor anything they merely substituted a rational US customary value.

When they change 2 meter social distancing to 6 ft it is censoring, they changed it to what they think it should be, otherwise if it were a conversion it would be 6 ft 6 inches. I wrote to the journalist to ask why it was 6 ft when she’s reporting from New Zealand, she wrote back and said that 2 metres was what was in her submission, someone in Washington changed it.

I see this is quite common because journalists are convinced the reading public is too stupid to understand an article that contains metric units only. Some publications are changing, but if more people such as yourself let them know you WANT to see metric units, it might have an effect. Better than having no voice at all.

I know Hospitals in the United States use kilograms and Celsius for all patients. All Pilots and Air Traffic controllers in the United States use Celsius *only* for temperature at every airport in the United States. Every mechanic who works on a car or airplane uses millimeters because that's what size all the bolts and clearances are. I could go on, many many people in the United States understand and use the metric system every day, except the Washington Post ! I believe in supporting good journalism, but I'm not going to put up with your censoring articles to omit the units I prefer.
