You had to pull me in on this, did you ?
It is astonishing how some people (not referring to any nation or sort of) are poised to protect their own miss..... whatever, not just the wrong system, but also driving on the left side while the rest of the world drives on the right, some nations and religions thinking they are goods gift to earth and that only they have the right to everything, etc etc.
There was a documentary on youtube about imperial system and the losses the US economy suffers from using it every year ( enter some random number here with lots of zeros ), but still refuse to switch to metric. It also had a nice showcase with 3 of the machinist that work for American Chopper, they spent 13 minutes trying to figure out how much should a pipe be cut based on the measurements of the space it has to fit and the length it actually is, they did not figure out, they gave up and just did it by eyeballing it.
And a gallon is not a gallon, an ounce is not an ounce, well there are several ounces.
Same goes for electricity, they still use 110V, requiring much thicker cables and transformers every 100 to 200 meters, not being able to use high power machines, not being able to quick charge the Tesla in their garage, etc etc, oh and lots and lots of fires due to the old way of installation, overloaded transformers, old types of equipment............. and the list goes on. I'll shut up before i delve into the way of building houses and materials used, and some other stuff.
I better go hide now.

I am trying to do what you have done and banish everything except metric units but other dont want to participate.
Example, we use a lot of Gal coated CHS pipe. The steel supliers call it by Nominal bore. But when we draw up the pipe in our 3D cad program we use mm, so 33.7x2.6 OD pipe becomes 25 Nominal bore in Light thickness. But the thickness designations with different size pipes do not line up. 48.3x2.9 OD pipe is called 40 Nominal bore in light.
It really does my head in.

But for the last 20 years, I banished Imperial units from my world and life has been good.

LOL, If I could I sure as hell would! RHS,SHS, Flat bar all conform to metric sizes. Pipe seems to do its own thing.

The conversion to imperial units is still roughly somewhere between an inch and the moon... which we landed on
In all seriousness, I agree with you all. It's just the way it is here, and there isn't much I can do but be assimilated... resistance is futile.

It does beg the question though. Why?
I was brought up with imperial units and the changover when I was 20 was relatively painless and metric is really easy.
I think someone with a bit of power over there needs to grow a pair and just do it.
