This topic could go on to become many pages long , I`ll try to simplify . Just
remember you did ask.
In the UK some things are measured in imperial and some things are measured in
metric. UK tape measures have both systems printed on them and will do so for
many years to come.
If you were to fit a new kitchen you would find nothing that worked into
inches, everything is mm.
If you buy Plywood it is generally 8 feet by 4 feet ( and a bit for some reason
)
Plasterboard is ether all metric or the smaller boards come 900mm wide and 4
feet long .
I do not consider myself a fan or critic of either system , both have a place
in the world , I imagine in the future metric will be the winner but what do I
care. for my work I require to be fairly accurate with length and that’s about
it. If I was a scientist I would use only metric
I constantly need to convert from one system to the other which can be a pain
but a pain that Im used to.
I have never heard the term `thumb` in all the years I`ve been trading, No
boards I know of are sold in 120mm or 2.4cm increments .we do have 2.4 Meter
lengths as standard size but that is only a close conversion to 8 feet.
I still ask for timber in feet and inches in my local merchant and they always
`correct` me in metric and I still go to my local pub and down a pint or two.
