yeah, i only mentioned the auto industry as that is what i am most familiar with. funny though back in the mid 70s when i was in high school, my chemistry teacher hated the metric system, but my physics teacher loved it. and my auto shop teacher didnt care either way.
Oh yes, in physics it gets a bit nasty, for instance with pressure where you have several units involved, so calculating is more complicated
I remember the push towards metric when I was a kid. A liter of soda was unheard of I was young but it was supposed to be part of the conversion process. I don't know why it stopped, it really should all be metric but with a side of the old ways for historical sake.
I don't want a large farva, I want a liter of cola.
Yes, it is pretty systematic, consistent, and scalable.
But even in Europe we still use some Imperial units, which historically have been used all over Europe. For instance we use inches (in German Zoll, in Portuguese polegada) for things like display sizes, tubes and fittings, etc. The pound is also widely used as a weight unit, especially with food.
The Olympics still throws folks for a spin trying to figure out how long say a 10K meter race is. lol
Metric from a mechanics stand point is a much easier system. less tools required because fewer sizes of bolts. The only thing that is difficult about the metric system is converting to standard.
But only when you pick the wrong order before the unit. Actually that is one of the benefits of the metric system, you just add a c, or an m, or a μ (which was not a lucky choice though as it is not a standard letter) or an n before meter. Is there something like a milliinch or nanoinch?

However, they will actually measure the weight in grams. It might be called a quarter ounce on the street, but I guarantee you they used a gram scale.
Ironically, a gram is a unit of mass, while the oz is a unit of force (weight). The metric unit of weight is the Newton.
