"Maybe the horses in the metric countries were a touch smaller and a little less powerful. haha "

We had a Shetland pony ( and some other animals ) when we lived near St Tropez, he was about 135 cms at the withers ( or a gnats nudger over 13 and a quarter hands* ) ..pretty big for a Shetland..

French horses small ? ..look up Percheron..
https://en.wikipedia.org/wiki/Percheron
Beautiful, big , powerful horses, I know some people who work with them, logging..

Note what jimmy's online encyclopedia site says about the Percherons ( and their size ) in the USA..

*Hands, another of the imperial "approximate, varied according to where you lived, now "standardised" at 4 inches, or 101.6mm"
or..you just measure horses ( and everything else ) in mm..for precision :)

I measure motors or the energy they use or can give out etc.. in Watts..or Joules..and or / or the "hourly" amounts ..

Hours..24 to a day..10 or 20 per day would be so much more simple..time and astronomical units.."light years"

Not like just "popping out" the the Chemist's** down the road..

Buy a ruler with mm and use it to do your measuring.

As Tom said. Poke ya head out from behind that pine tree in Mississippi and find a hardware store. Great things there await ye

I learned to use metric measure in the machine shop. It is much simpler and more accurate. Easier on the mind when you embrace it. Metric scales of varying sizes are your friend. They are fairly inexpensive. The better one do not live at Walmart. I would suggest a good etched set with cork backing from a office or hobby shop,

sorry, but a simple 1 dollar ruler and no more math headache.

Just realised..even here in metric country, I still buy leather in square feet..The length and width of the piece / skin / hide is given in cm or occasionally in mm..But the price is quoted and invoiced in square feet..Thickness ( weight ) is given in mm.

Go figure..pun unavoidable.

Yeah same here. Guess 20 square feet sounds better than 1.85 sqm . Its them damn ounces that get me most.

Tangential, but very important :)..Do you buy draught beer in pints or litres ( or half litres ) in Australia ?..Thinking about the size of your Croc beer holder stuff ( yes, I forgot what you call them ; ) ..

Ounces ( leather "weights" ) I ignore, or transpose to mm thickness without thinking about it now ( work in mm ) ..even carats went metric..1 ct = 200 milligrams, 5 cts per gramme.

What gets me is Engineering thread sizes and pitches, nuts, bolts, screws etc*..and especially old Singer threaded parts..world of their own :(

*Have to have so many tools to deal with British , USA and metric..and some metric used to have weird threads and pitches before they got standardised.

"Love these base definitions that nobody can understand!"

Nobody ? ..The "base definitions" are part of physics, the more we understand, the more precisely we can measure.

So I guess you can visualize "the metre has been officially defined as the length of the path travelled by light in a vacuum during a time interval of 1/299,792,458 of a second."  I can visualize many things, like electrons (or holes if you like) flowing in an electrical circuit, but to visualize how far light travels in 1/299,792,458 of a second is beyond me.  Your definitions for an inch can be easily visualized for a rough estimate.

I have no problems with English (Imperial) or American units, nor with SI units.  I work in all three.  Have taught (for 19 years) engineering/technical folks in both Imperial and SI units for years.  Converted many tutorials, lab assignments to SI units as we adopted SI in about 1979.  Re-derived formulae using SI units.  Have worked in the EPC industry for 20 years using whatever system the client wishes to use.  I can flip back and forth at will.  You should look at Pipe Tables if you want to see a real mess.  No one is ever going to change the dimensions on 2" pipe, nor the threads associated with it.  But 2" pipe is called 2" pipe, though I see some people trying to call it 50mm pipe.  But that should be 50.8mm pipe!  Makes a lot of sense doesn't it!  Also pipe thickness is given as Schedule 10, 20, 30, 40, etc.  No reference to Imperial or SI.  It's just a crazy world.

I still think the best conversion system for those without SI Metric abilities is to use 2 rulers, laid side by side.  Gives excellent visualization.
