Just need to vent...

Then you have your minutes and seconds of degrees. You do get used to it though when measuring.

 

All of us wackies that do geocaching need those measurements
as well

.

 

Yep ! since here in Canada , we adopted ....or forced to adopt the metric system ...Strange units made it quite complicated . Instead of going all in at the beginning ......some units of the imperial units are still being used today in some conditiions.
I think the worst one is the one on the price of meat . Here is what i want to show . ...usually the price of beef is usually in dollars per kilos ....IF it is on a special sale ..the price is expressed in dollars per POUND . Numbers are quite different ..what a joke.

 

Yep another strange unit ,imperial gallon versus a US gallon

 

How about Mpg e ......another strange metric for us canadians ....where litre per 100 km is the official metric
and is converted in Le/100km ...brain gymnastic.....converting the equivalent in Khw/h of energy of a litre of gas...one litre of gas is the equivalent of 8.9KWh of energy......my brain is tired

 

'Shrinkflation' has given us numerous products in non-round quantities too, though not nearly to the extent that you find north of the border.

 

I'm still PO'd about shrinflation of a ½gallon of ice cream.
& that was decades ago

 

The old 5-quart buckets of my youth are probably today's pints.

 

"The designers of the metric system were starry-eyed idealists"

Oh my dear sir. Metrology is about mass, length, time and temperature. First three are married (if a triad can be called so) in a pendulum, a profoundly tangible device long known. It was brilliant (and curmudgeonly) Newton, I believe, who sanctified that marriage with Calculus. Definition of each unit had histories of their own.

Mesopotamians 5 thousand years ago thought in terms of base 60. Days are of consistent length; divide them thus and so and get seconds. Defining measurements of length could be, well, anything. Three grains of barley could be an inch. A man's forearm length cubit could be a foot. One ten-millionth part of distance from earth's equator to pole could be a meter. Metric system set aside barley and human anatomy in this. Mass remains after defining time and length, and a cubic meter of (very earthly) water weighs 1000 kilograms.

So I say it was not at all starry-eyed. Earthly in every way. Classical physics, statics and dynamics; Galileo and others developed relationships among these. Equations don't care what units one uses, but metric units are clean and consistent.

Last we come to temperature. And water and the element mercury. Water freezes and boils at different temperatures, and as mercury trapped in tubes expands with temperature, it can inform. Celsius set that range to 0 to 100. Fahrenheit went elsewhere.

For reality (of physics) on earth, ANY units could be used, but the simplest and most self-consistent are IUPAC MKS units.

US, Myanmar and Liberia hold back from metric adoption. Readers should judge where which "idealists" might be backing the wrong horse.
