I was astonished to find Americans actually call plasterboard

Daft in the first place to say "drywall", as all walls are dry,
unless
made of mud, which is still dry once it's set.

Lath and plaster with horse hair is a wet wall....


They say two by four as well ....

I always thought they called it SheetRock ?.

I still buy 2 by 1, but the blasted stuff sold
as PAR (planed all round) is nowhere near 2 x 1.

Local builder's merchant here sells what I ask for.* They have several
sizes.
oooh lucky you .... four by two is the rough sawn size....when
planed it
is smaller....

Mine sells by the mm.* They quote on the website the precise size it is
when you buy it.* Why would I want to buy a rough size which may not
match what I already have?* Your houses must end up really wonky.
It's just just they way things are.....

Don't accept inferior products.* If you buy something that's supposed to
16 of something, and it's 15, that's not fit for purpose.

Since when has the building industry worked to the nearest millimetre?
To the nearest 100 millimetres more likely.

They've started selling metric plywood up here - and it's pretty
accurate in measurement - but inch plywood always was too. Now the
problem is 15mm isn't exactly 5/8 and 17 mm isn't 3/4 - and sometimes
they are substituted -- - - Some of it is also metric length and
wirth instead of 48X96 inch (4x8)

Dimensional lumber is still sold as 1X and 2X 3, 4, or 6 etc
"nominal" even in "metric" Canada - and you still buy 6 foot or 8 foot
or whatever lengths. They also sell "stud length" that are precut to
the right length to fit between upper and lower plates to make an 8
foot wall (92 5/8 inch long)
