We’re taught both metric and US customary units in school. I prefer metric for most things, to the point I have a metric-only tape measure among other things.
However, I’ll die on the hill that Fahrenheit is superior for ambient air temperature. 0 degrees to 100 degrees neatly encompasses the range of average surface temperatures seen throughout the year in the contiguous US.
I tend to use metric when I’m designing 3D models.
In woodworking and other linear measurements, I use imperial units.
Celsius for my 3D printer, but Fahrenheit for weather.
Driving is miles.
In cooking I use imperial units.
Metric for Physics.
When I see imperial units in high school physics I wonder what is the point. We typically use SI units so that constants are the same across the board. I can’t imagine c being anything else other than 3e8 m/s.
I remember my sophomore thermodynamics class in college always seemed artificially hard because the only really difficult problems were ones where they decided to use fucking BTUs.
I’m reading the wiki and that sounds like hell. I prefer the 4200J/kg/K edit: wait that’s just heat capacity, maybe you were stuck in even more hell.
Scientists and physicists go in to use metric in work. US Engineers often go on to use imperial. Slugs and kips are units somewhere in there. But the engineers that calculate with gravity tend to be back in metric
