I love it the metric system for liquid measurements and for a tape measure and thats it.

Actually there are only two types of Countries on Earth. Those that use the Metric system and those that put men on the Moon.
It's called a joke, people, but I still prefer Imperial. I'm old enough to remember seeing the moon landing on black and white TV.
The US does use the metric system, as all units' legal definition have been in terms of the metric system since 1893. See https://nvlpubs.nist.gov/nistpubs/Legacy/SP/nistspecialpublication1038.pdf
I keep nothing but SAE wrenches and sockets at the hangar and separate toolbox drawers for SAE and metric at home.I use both daily. Working on airplanes, especially those with Rotax engines, I have to have complete sets of SAE and Metric.
Main use of the metric system by Americans is when we want to shoot someone.
One advantage the SAE system has over metric is that the screw sizes make so much more sense. If you are wondering what the screw is measure the diameter and count the threads per inch; with metric screws that don't work so good.
When I worked as a draftsman at Kaiser I had an Engineer tell me "with Metrics we could be More Accurate"
This was someone who found it difficult to find the exit of his office!!!!!!
I'm more comfortable with Imperial too. I am, however, becoming more fluent in Metric. My ex has grasped the concept of the mile.Actually there are only two types of Countries on Earth. Those that use the Metric system and those that put men on the Moon.

FWIW The Chrysler Imperial was my favorite car when I was growing up. No foolin'.
And the US picked up them Mile markers.Which was a Roman metric measurement. 1,000 paces of a Roman Legionary on the march. Britain took the mile as a standard, and probably as its very first standard, because the Romans left thousands of mile posts spread all over the Roman controlled parts of England so they were already there and did not need replacing. Some are still in existence over 2,000 years later.
They always know where you are.
!!!!???!!! Must be nice to have a LASER INTERFEROMETER handy to measure such teeny tiny things! And you do not have to count a whole inch worth of threads. A quarter inch or so will do fine.the distance between each thread in mm

You have to be careful with torque wrenches to make sure you are reading the correct scale for those that have both. Some years ago the USAF went through eradicating all torque wrenches with Metric scales to make sure of that.

Saw where some guy said the US will never ever go metric. He said all those little screws used to secure switchplates in US homes do not have a metric equivalent.
I had one odd thing occur. I was replacing the voltage regulator on my Toyota and overtorqued a mounting screw. The regulator was secured using some rubber grommets and thus the screw did not get tighter and tighter but just broke. So I removed the remainder of the screw and went to a large, very old fashioned hardware store and told them I needed another. The guy measured it and told me it was 1/4-28. I was very surprised, since I figured it had to be metric. So I bought a 1/4-28 screw and took it home, where I found it did not fit the car. Turns out that the original metric screw got stretched out by the overtorquing to essentially the same as a 1/4-28.
