I'd be all for adopting metric for everything, if it could be adjusted to Base 12, which is much better adapted to human behavior and more amenable to simple arithmetic.

An engineering professor one had yonks ago stated the proper system would be one where the gravitational constant was unity. People wish for what makes their own lives easier.

Well, one could see his point.

One ten-millionth of the distance from the Equator to the North Pole (in 1793) is no more or less arbitrary than the length of the foot of the reigning monarch, or the cubit & span, or the various sizes of containers for transporting ale. And what ever is gopher wood? Nobody seems to be certain.

Another physics professor had a lab coat he wore around which was emblazoned with: "Nobel Prize Runner-Up". Turns out he wasn't having us on at all. He had discussed the propagation of the speed of darkness. He tried to explain it once to our class. Well, that was a mistake.

As it was we learned kilograms and slugs for mass, newtons and pounds for weight, 9.81 and 32.2 for gravitational acceleration. And the Inuit have dozens of words for 'snow'.

F=mA. Derive the rest.

Base 1 is very popular nowadays.

Oh, and then there's Calcomp plotters. They're in inches, or centimetres, or millimetres. No way to ask which, you just have to know. Run some software written for a millimetre based plotter on an inch based plotter and watch the pen holder smash into the end stop at full speed as it tries to move 25.4 football pitches to the right.

Except that it is not square.and it is not even close to a square metre.
It is, by my calcs, 499554 sq mm (let's say a half (no, let's say 1/2)) lets say 0.5 sq metres.
And its dimensions use the ever forgettable ratio of 1.415825 : 1.

And unfortunately, the base unit (A0) is nowhere near non-existent (0 sq metres?).

Especially if you are still using shillings and pence.
Or if your mother was Tasmanian.

Paper sizes. A0 is 1 square metre. A1 is half that, etc.

The shapes are not based on the metric system, sorry. They're based on the golden rectangle, which far predates the metric system. Yes, they decided to base the reference size on the area of a single square metre, but it's not inherently a metric paper size.

Fibonacci. Check with him, he'll explain it, but you're confusing ratios with a reference unit of measurement. Not the same thing 'tall.

Paper Sizes

Good honest pounds, inches, and slugs put man on the moon. My engineering education used both that system of units and SI, or metric units.

I thought everybody's did. After all, the slug connotes mass in a system known as British Engineering units. Are you saying that the Yanks know your system better than you do? It would appear that you are saying that indeed.

You lot bang on about needing to take off a stone so your trousers will fit and get upset that a U.S. pint is smaller than a British pint while jailing greengrocers for selling bananas by the pound. Make up your minds, can't you?

We really are stuck in no-mans land between Imperial and metric in the UK. Back when I was teaching I used to casually ask pupils how tall they were or how heavy. These were pupils who had never been taught anything other than the metric system of weights and measures, but they would invariably reply (eg) 5 foot 3, or 8 stone 6. Ask them what that was in metric they wouldn't have a clue. Also if you go to a builders' merchants and ask for a 2 metre length of 4 by 2 they wont bat an eyelid. And yet we seem to manage.

The metric system wouldn't be funny at all, when Mae West asked a man how tall he was:
"I'se 6 foot, 7 inches, ma'am."
"Forget about the 6 foot, let's talk about the 7 inches..."

And like most Brit sailors, I think of boat lengths in feet but draft (and depths) in metres! eg describing a 38 foot boat drawing 1.2 metres!

At sea, all depth and air draft calculations are purely in metres - why does the flying world stick with feet?
And wind speed is a mess. I think of winds in knots, but many (most?) outside UK think only in m/s.
And what about QNH in Inches Hg vs hectopascals ? That's really crazy to run two systems in parallel.

Unfathomable.

Double m/s, she's close enough so long as you're subsonic and not doing research.

You really need to fly helicopters somewhere that uses QFE and switches to QNH and has ample opportunities for off-aerodrome landings that are significantly below sea level. There is something sublime about the barometric altimeter passing through 0 when one is still high enough in the air to get badly hurt.

All of these things are designed to keep out the riffraff.

There is also a system based on a single standard, the Smoot. The various dimensions are those of a student at MIT who devised the system.

Unbelievable.

A thread discussing the issue of mass murders in the US turns into more concern about measures, sizes and date formats.

Humanity really is made up of retards.... (posted deliberately because I know the snowflake blizzard that word creates even when applied correctly.)

Incredible

Outcry after police shoot African-American security guard 'hero'


https://www.bbc.com/news/world-us-canada-46187460


So if the solution to shootings in schools is to arm teachers, better make sure you only arm the white ones.

There clearly is a fundamental problem here. The militarization of the police, who are prepared (dare I say expect) to engage in a gun battle on every call is one of the drivers of this mad spiral.

On a good note, my state just implemented a "red flag" law. Now, if someone displays worrisome behavior, a judge can have all their guns removed. Since the Supreme Court would ultimately protect against abuse of this law, I'm ok with trying it out.

This is routine were I live in Australia, but the process is automatic not requiring the input of a judge.

This expedites the process, but also leaves it open to abuse. For example, a vindictive spouse/ex spouse can make an unsubstantiated claim that will see police obliged to confiscate weapons.

Not sure of the numbers but I think within 24 hours for a period of 5 years (?) then a review process can be undertaken for return (?). Someone may be able to jump in with more knowledge there.

Certainly a safety valve for criminal or mental health concerns, however "patient confidentiality" makes this problematical.

You post caught my interest.
Is this the one, or a different one?
