There are “something” for a lot of things that are not in metrics.
Like tire sizes. My bow’s power is measured in pounds (and I should use inches there too normally. I don’t bother.) Screen sizes are in inches I think…
95% work in metrics. But there is always a little stuff in some weird units.
Yes, only places where it is mixed is the anglosaxony… try to open to the world.
I use pounds because I do archery, where my bow’s power is measured with that unit, which I translate as 1/2 a kg. I don’t care that it’s inaccurate.
There are also inches (I think) for Tv and computer screens, which is shitty.
But no one else uses imperial.
I worked with croncrete blocks (prefabricated building elements) some years ago and I was all the time making fast calculations of sizes and weight and I cannot imagine making that in imperial (admittedly because I am not used, but in present case it would just have been massively impractical)
The vast majority of the world does not use imperial units.
14$ per month looks pretty expensive.
