Convenience of the metric system

[carstenb]

Just to keep things moving along - think pipe and fitting threads

NPT
BSPT
BSP
Metric

and several others that I can't remember offhand.

Oh - and the same goes for bolt threads - there are a multitude of those

There is one heck of a story behind that design, but I'm sure the rest of the world is scratching their head as to what the heck a Robertson is.

Best screw head ever invented... saves a LOT of scrapped fingers.

Hey, you forgot the Tri Wing and Quad Wing

Thanks for the heads up! Sad to hear, but good to know.

Robertson? Oh you mean square drive screws.

The head of a Torx, for example T20, where do the number comes from? 2.0 mm?

More importantly, why does my Furlex have three different sizes of torx screws...

I do not live in the USA. My car was made in Canada, all metric. :-)

How convenient. Save money and have half the size tool box to carry around. I'm envious.

Guess there are some benefits to living in the land of ice and snow.

And the temperature is in Celsius, so we don't actually know how cold it is. :face palm: That's actually an argument I heard against converting, many years ago.

(Although for those who don't know - minus 40 is the same in both systems. Yippee!)

That's also one I don't quite get myself. I always thought temp was one of the easier metric.

Freezing zero, boiling 100, hot day 30, nice day 20 cold day 10.

If there is still any confusion open a window and stick your head out.

In principle, I'll use any system that's well defined and consistent. I grew up in Imperial, gradually switched to metric as the country did, and while studying Engineering learned to work with either.

But in reality I find that, with time, I have lost the concept of temperatures in Fahrenheit. And miles-per-hour, when I visit countries that use it, is starting to give me trouble.

When I go to the butcher I order in grams or pounds depending on how I feel that day. But I bet my daughter has no idea what a pound is.

So it's mostly what you're used to, but the human brain is remarkably adaptable - in spite of what some people appear to believe - and can generally deal with whatever system is in place.

Don't know what you mean. Little ice and snow on our part of the north sea. 😀

True in the vast majority of cases. But it's clear from certain posts on this thread that some human brains are not adaptable at all

Finally!
Two posts on this thread I can totally agree with

Although if pushed, I might add that while our local butcher is good with pounds many around here only know kilos…

Daughter thinks a pound is some sort of money used somewhere else
