Maybe this could have gone into the other thread, but I’ll start it as a new one.
An older complaint that I heard about the metric system was that when the US would finally go in for more complete conversion, there might be various incidental PITA issues coming out of the, er, woodwork. Wood frame construction is very common in the US, particularly here in the west. Typical stud spacing for walls is 16 inches; I’m aware that it can go up to 24 inches in many circumstances.
Plywood and gypsum wallboard sheets come in various compositions and thicknesses, but a very common sheet size is 48 inches by 96 inches, or 4 feet by 8 feet. This fits quite well with the common stud spacing, don’t you know.
Many of you know where this is going. When the US goes more completely metric*, stud spacing will likely change to 400 to 600 mm. Four studs at 400 mm will then be 1200 mm outer to outer stud center, or about 47-1/4 inches.
Will that cause issues with getting the current common size of plywood and wallboard sheets to ‘fit’ properly? If the plywood sheets are likewise reduced in size, won’t that cause a problem in retrofitting the older homes with the slightly greater spacing?
Or is this just something that carpenters would just work around?
How do you deal with this in Canada?
*Well, for one thing, we are partly there, what with soda and liquor sold by the liter, and metric auto wrenches, and 5 k runs, and such. That, and I think that someday we’ll finally get tired of hassling with 5,280 feet per mile and 43,560 square feet in an acre, and all that.
