Metric?

As we all know, we didn't really go metric, just token metric.
e.g. what was an 8' x 4' of plywood is now a 122cm x 244cm. If we had gone metric it would be 120 x 240. Or even 200 x 100.
But I still think "I need an 8 x 4 sheet of 18mm ply" or conversely "2.4 metres of 2 x 1.
But how are sheet materials sold in Europe? In 122 x 244 converted from the old Imperial system, or 100 x 200?
I'm guessing Europe uses 122 x 244 because the USA probably dominated the sheet materials market?
Must go. Nipping down the pub for a couple of 568mls.

Is that an ironic site, because it just sits there indefinitely on my machine?

Chance would be a fine thing, but I suspect the usual triumvirate of location, location & location come ahead of decent broadband. That being said, I don't think I've seen anywhere with *slower*!

Many things like that are made in a size arrived at over the years.
Not much point in changing say plasterboard to a nice round metric figure if it no longer fits existing stud centres.
Imperial measurements were based on the human body - so no surprise building materials are in a convenient size relative to that.
Metric is more of a scientific or theoretical measurement. There are pros and cons for both. My guess is the change to metric made it easier for early computer systems to calculate. But not for humans.

Well, my index fingers are very close to 100mm long, little fingers about 10mm wide at the tip. If I stick my arm out to one side and turn my face away, the dist from the tip of my middle finger to the end of my nose is close to 1m.

I don’t believe that was significant. Calculating with metric units is easier for humans, if perhaps more prone to slipping into the wrong band of unit, but that”s a problem with the naming system rather than the relative sizes of the units.

Eh? Trivial job to use a calculator etc with metric systems. Different matter with yards feet and inches.

You'd be amazed how many 'average' people don't seem to be able to differentiate between mm and cm. Don't remember so many getting confused between feet and inches and fractions of an inch.

The thing that annoys me is medics using 'mcg' for microgrammes instead of 'ug' (or µg if that works out). I wonder how many massive over or underdoses have been covered up.
It also annoys me that they use 'fluid' instead of 'liquid', but there's less scope for harm there. 'No fluids' would be a tough one.

Probably no more than any other possibility to be confused by units. If that is the convention in a particular field then it's fine.
My wife is doctor, but I've no idea what she does re this.

Ever considered being less annoyed ;-)

You have this backwards. They switched to using mcg because it is more different from mg than (handwritten) µg.

I remeber when a calculator came out that could do fractions.

Maybe true but them cm isn't a true SI unit.

Probbaly due to a few generations practising, but my mum could never work out what a third of anything was. And as for fluid ounces and hectares to fathoms on to grains and troy anouces. How about short tons and long tons ?

Ah. I don’t think of “a calculator” (as existed back then) as a computer system.

There were calculators that could do that.
