USA uses US Customary units, not Imperial units.

Fahrenheit is grouped with US Customary units but is not one.

I agree metric system is superior and there isn’t a reason to use Inches, Feet, Yards, etc.

But Fahrenheit is a great system for weather and works great for everything else.

For science if I have to heat a beaker to 280° it doesn’t matter if it’s C or F. I’m not going to be able to relate to 280° in either system. The instrument is going to have to tell me the exact measurement.

Same with like a tape measure. I can measure out 3 meters. I don’t need to know how long 3 meters is to do that.

However, mark two lines on a piece of paper and I will get closer guessing in inches than cm because I know the US customary units better.

Eventually US will change to metric. But I doubt we will ever not use Fahrenheit for normal day things like weather
