Why do some countries or organisations stick to this archaic system whereby you have to calculate how many smaller units make up a bigger unit? And it differs depending on what quality you are measuring.
For weight we have 16 ounces make 1 pound, 14 pounds make 1 stone, and 160 stones in 1 ton. Then for distance we have 1 inch (which is divided into 16ths), 12 inches make 1 foot, 3 feet make 1 yard, 1760 (wtf?) yards make up 1 mile!
Can we not just stick to moving the decimal point up/down or would that be too hard for all the people who grew up in the bronze age? I really don't understand peoples arguments for it, OK you may have been educated with this system and had to use it before the government change (most) things into metric, but ffs we don't count in binary in our heads, so why is simply 1/1000th, 1, 1000, so hard to understand? It's how we were taught to count! When we were 2! Before we even knew what a measurement was!

If it was a test based around using this system of measurement with no guidance then yes, I would do very poorly.

and those of us brought up with this archaic system have no trouble at all converting to metric because we were taught both systems at once. The complaints are from those, like yourself , who struggle with maths as opposed to moving a decimal point.
Also the system we learn becomes embedded over our time as a kid (surprisingly even old people used to be kids).
So I can visualise a mile (better not say furlong) a yard or 70 degrees Fahrenheit but if it's presented in metric I have to do a conversion in my head
Don't worry about us though. Back in the day we were taught mental arithmetic and many of us can add up a column of figures quicker than a calculator, metric or imperial.

That's a different answer to a different qotw! But my issue it's with organisations (and I include governments) Who have this as their system of measurement. Why make things harder than they have to be? We don't use shillings etc anymore for that reason.

Says seven replies...but when I pop in to have a look, there are only three to read! Fascinating.
And with all the excitement this has caused, I've forgotten the point I was going to make about the metric system.
Something about bananas I think.

It is surely easier to use a system which at least has a base number

It is a system of numbers which has no base. Therefore it's irrational.

Slavery suited it's users needs. People in this country didn't always speak English, or use the latin alphabet. Using horses as a form of transport was the best way to get around for millenia. Are you saying we should just ignore any improvements or additions humanity makes? Bah, houses! Living in caves was good enough for early man etc etc...

and asked to measure a piece of machinery so the transport company would have dimensions. Apparently the road roller was 3 metres and 10 inches long.

Cross-section imperial (with metric equivalent), length metric. Due to older houses being built imperial and needing imperial replacements.

You can't buy 2m of wood in Polish B&Q. You can get 1.8 or 2.1m through, which is oddly enough 7 or 8 feet.

Feet you see.

That's just a case of basic conversion. It's not particularly any more difficult or easy to have 16 things in another thing than it is to have 10.
Gravitational unit systems are what you need to worry about, so I think we can all join together in slating the American Unit system.

is a lot simpler than doing so by 16.

In so far as doing any of this stuff in your head.
However, in the reality of unit conversion in engineering it doesn't make that much of a difference. As opposed to having to introduce an inverse graviational constant into every single fucking law of newtonian mechanics, which does.

pound-mass and slugs.
Luckily most engineering calculation involves tables and programs.
Basic calculations are something to harass students with.

but in reality these days in most scenarios, no-one does, and no-one does.
When I lecture this stuff I do fall down in favour of the boy Panzer, in that imperial/US units are a bit of a pain compared to SI. But the conversions are really only a minimal inconvenience when everything is done with a computer.

...because one part was programmed using the obsolete "imperial" units while the rest was in metric, I've noticed a definite shift toward metric, at least as far as American science TV goes.
It amuses me that the American people think of themselves as the most advanced nation on Earth, but still want their car to do "14 rods to the hogshead", as Grandpa Simpson so eloquently put it.

I use it as an example in lectures, but not specifically as a flaw in units systems, but of the importance of communication and proper unit conversion.
